Why these extreme multihull concepts could be the future of catamaran design

• October 13, 2020

Holiday homes, restaurants, even cities may soon be coming to a quiet beach or harbour near you, reports Sam Fortescue

The €500m beiderbeck-designed Galileo2 concept catamaran takes multihulls to another level and is capable of berthing yachts up to 80m

As boats become ever more like homes on water, something else is changing: designers and builders have been turning their attention to the market for floating buildings. New concepts to emerge range from a thatched beach cottage atop a catamaran hull to an entire floating city, generating its own food and power. The one thing they have in common is they’re movable structures that can be parked wherever they can drop the hook. And soon they could be coming to a peaceful estuary near you.

There is an opportunity here, of course, to create additional living and leisure space in areas where the land is already choked with people. Imagine being able to moor a temporary holiday village off Bournemouth Beach, for example, or create a restaurant off Dartmouth without affecting the townscape.

But the flip side of the coin is that someone could park a large floating structure right in front of your sea view, or occupy a quiet, sensitive environment. Imagine, as sailors, falling asleep in a deserted anchorage and waking up with a throbbing beach bar right next to us!

Floating homes and docks are being designed to use Seafloatech’s eco-friendly anchoring system

“If a craft is movable and can drop an anchor, it would be classed as ‘any other vessel’ and would not need consent,” confirms Martin Willis, executive officer of the UK Harbour Masters’ Association. “But if it’s a commercial business, it’d be subject to the relevant regulation – there are no rights to come in and open a business in a harbour without the Harbour Master’s consent.” Alternatively, it may fall under MCA coding as a passenger craft.

In some parts of the world, floating structures are already quite common. Upscale luxury holiday resorts in Thailand or the Maldives, for example, offer floating villas. And soon you might expect to see whole floating marinas if you find yourself close to St Tropez. France’s recent move to protect crucial Neptune grass meadows in the Mediterranean means that anchoring off the town is severely limited for yachts over 24m.

To get round the problem, a company called Seafloattech has developed a system of screwing steel frames to the seabed to moor big structures on giant hydraulic shock absorbers. “We had a prototype size in place for six months in the Bay of St Tropez,” says managing director Lionel Péan, the French ocean racing star and past winner of the Whitbread Round the World Race . “It could accommodate up to 70 boats in a maximum wind of 42 knots, with up to 2.4m wave heights with no structural problems or injuries.”

Offshore developments

The hydraulics keep the marina on station despite the tide and help to counteract wave action. It is even possible to use the system to tether a boat or a home through storm-force conditions, insists Pean. “If you want to build something to resist a typhoon, for instance, you have to make special arrangements with the customer. It can be done, but it costs a lot. In the Med, you don’t need 5-6m waves resistance.”

Seafloattech itself will ultimately just licence the tethering system, but it is working with partners who envisage all manner of structures atop their platforms. There are swimming pools, beach clubs, superyacht berths, hotels and villas.

“We believe that the demographic surge will force the coastal states to really focus on offshore coastline development,” adds Pean. “I am for a two-fold operation including sanctuary areas and social offshore development zones. We think that Northern Europe will take some more time but as soon as we have some units up and running, it will happen quickly.”

Seafloattech has developed a steel tethering structure that is screwed to the seabed with hydraulic shock absorbers that can secure any number of floating homes. Standard versions can cope easily with Mediterranean weather conditions

Another French concern, Faréa, has taken a markedly different approach, developing a home that sits on two deep metal floats that also contain cabins. It is a simple catamaran, propelled by an outboard at the ‘stern’ and anchored with normal ground tackle at the ‘bow’. Navigation is slow and only for fine weather, but retractable centreboards mean it can be beached.

“They amount to 86m2 of space, with seven double cabins separate heads and bathroom and three terraces,” explains founder Christophe Roi. “They are self-sufficient in water and electricity, thanks to the oversized photovoltaic panels and fuel cells.”

A thatched roof multihull?

The original plan was for something more like a floating house, but feedback from insurers pushed Faréa towards a craft that meets category C of the Recreational Craft Directive. “It means they can stand up to Force 6 and 2m waves,” explains Roi. “What with rental prices so terribly high in England, I am certain that living on water should be a possibility.”

Original Faréa concept was for an economical floating home with a thatched roof, but later versions can meet RCD Cat C

A fully equipped F2C model would cost around €160,000 to install, he adds. With the average Newquay home costing £730,000, according to RightMove, he has a good point.

Alva Yachts offers more architecturally ambitious 45m2 holiday homes with an infinity pool and a terrace. Not self-propelled, costs range from €85,000 to €200,000 depending on finish. The fledgling German company is using its founders’ experience of building catamarans that run on renewable power to offer low-carbon homes.

“The floating homes are literally super luxury yachts without propulsion,” explains co-founder Mathias May. “The hull and ‘sails’ are made of composites, while energy consumption, supply and distribution is comparable to a solar yacht. We strive to be as efficient as possible to get rid of diesel gensets in remote areas. It is no coincidence that our first customer for such a project comes from the Maldives.”

This ocean resort features a number of Alva Yachts floating eco holiday homes costing from €85,000 to €200,000

Meanwhile, two Finnish companies have developed a series of even larger floating structures whose near-total self-sufficiency allows them to remain offshore indefinitely. Architects Sigge and builder AdMares have turned the world’s largest floating villa (all 6,000m2 of it) in Abu Dhabi into an autonomous boat capable of tackling waves up to 1.2m.

By fitting a wheelhouse and three Rolls Royce US 55 FP azimuth thrusters with a total 750kW output, the villa can move itself around the sheltered waters of the emirate. An anchoring system at each end of the platform is equipped with whopping 38mm chain and 1,575kg anchors.

Off nearby Qatar, the Finnish firms have been hard at work installing 16 floating hotels with a total of 1,616 rooms, aimed at providing temporary accommodation for the huge influx of football fans due for the 2022 World Cup. With four storeys including a lounging area and a restaurant, each hotel can simply be towed to a new location after the tournament. The only restriction is the 4m draught.

This Oceanix concept sees hexagonal clusters of floating homes linking up to become towns with net zero emissions

Floating towns

Several orders of magnitude further up the scale and you reach floating towns. Some concepts, like Oceanix, are very serious attempts to expand the boundaries of human habitation to ‘the next frontier’. It is a consortium of companies focusing on the UN’s ‘New Urban Agenda’ with a plan to build homes on pods clustered in hexagons, in turn clustered into larger hexagons, and so on, up to cities of 10,000 people.

Their vision includes parks, arenas, restaurants, offices up to three stories high and built-in docking for solar-powered watercraft. Energy is harvested from waves, wind, sun as well as algae bioreactors and more to create a net-zero consumer, while food is grown on and under the city.

“We believe humanity can live in harmony with life below water – it is not a question of one versus the other,” says CEO Marc Collins Chen. “The technology exists for us to live on water, while nature continues to thrive under. Floating cities by design embrace all types of marine activities, so they are complementary to existing activities like fishing and sailing.”

Nomadia is a multi-deck craft for 3,000 guests. An alternative to cruise ship holidays, it features an internal marina and even beaches

The initial sites envisaged for a city are all on the fringes of the Tropics, from Japan to Thailand, and the structures are designed to withstand Category 5 storms.

A more Eurocentric view comes from two designers of cities on boats. French naval architect Sylvain Viau has developed an outline for a triangular craft measuring 372m in length, with a jaw-dropping beam of 369m. Across 12 decks moving at up to 5 knots, some 3,000 guests can be accommodated, along with lecture halls, meeting rooms, restaurants, shops, manmade beaches and an internal marina capable of berthing ten 100ft yachts.

Fun and games afloat

These giant ‘craft’ are nothing to do with loving the sea or even respecting the enivronment. “People are not interested in the sea, they are interested in casinos, cinema, fun entertainment,” Chen explains. “In my imagination, you welcome everybody on board in a nice location. The platform doesn’t move during the season, only in the winter, when it’s time to find a new spot.”

With yards promoting designs such as this BlackCat 50m, superyacht multihulls look set to be the next very big thing

At anchor, giant inlets like gills down each flank would channel waves into a generator to produce energy. And when it’s time to move, the boat raises its 300-tonne anchor and blows out its ballast tanks to reduce its draught from 20m to 11m.

Germany’s beiderbeck designs recently made headlines with the publication of a €500m concept catamaran called Galileo2, capable of berthing yachts up to 80m, and offering a fold-down restaurant and an open-air amphitheatre cinema. With a nod at managing greenhouse gas emissions, this small floating town would be powered by gigantic fuel cells, and would pioneer so-called marine thermal energy in yachting.

“You can use the temperature difference between the deeper and surface water,” explains Timo Hartmüller of beiderbeck. “Obviously, you need to be in deep water, but we designed the yacht to stow a 1km long hose on board.”

Some of these floating titans may never make it off the drawing board, particularly in view of the way that coronavirus has decimated the cruise ship industry. But the current is running hard towards extending communities above the waves, and whatever you may think of these concepts, be they luxury pads or modest holiday cabins, expect to see more of them coming to a stretch of coast near you.

Mobile pontoon

Multimarine near Plymouth is nearing completion of a 108ft x 28ft motorised platform called the Gweek Pontoon, which the owner plans to charter out for use as a mobile regatta and watersports base.

It is fitted with an anchor and windlass, as well as three 200hp engines, and includes a built-in hydraulic slipway. It is built from foam-core vinylester laminate and carbon fibre for light weight and a trifling draught of just 100mm.

Blue Coast 65 Sailing Catamaran

The Blue Coast 65 is a new, modern, fast and luxurious performance sailing catamaran for a smaller crew who want to enjoy worldwide cruising on all oceans.

Description

A dynamic "full-custom" design by our Naval Architect Jean-Jacques Coste, who has been recognized worldwide for his fast sailing performance multihull yachts for many years.

2 half-height helm stations provide sheltered positions. In bad weather, the yacht can be steered from the inside steering position in the saloon.

On the spacious flybridge with generous sunbathing areas and a dining area you can enjoy the sun, the steering positions can also be placed there as an option.

The very spacious main deck offers an enormously large, comfortable living area:

The forward cockpit area is directly connected to the saloon with a watertight door, the perfect place to find peace in port. 

The saloon with a comfortable lounge area and a fully equipped kitchen in a U-shape is a great place to be, with a bar counter in the middle with a retractable TV.

The shaded rear terrace is larger than the saloon and is probably the most popular place to dine, relax, welcome guests and friends. An outdoor kitchen can also be accommodated there.

On the cabin deck, a spacious master suite with bath and shower, a crew or single cabin that can alternatively be set up as an office or walk-in wardrobe, 2 guest cabins and a workshop offer a high level of comfort.

The forward storage compartments provide space for the washing machine, supplies, sails and equipment.

The layout of the flybridge, main and cabin decks can also be customized to suit your requirements.

Available with traditional diesel engines or with the innovative electric hybrid system "Green ECO Power".

Design according to your ideas

The design of the BLUE COAST 65 can be adapted to your ideas as you desire in terms of number and layout of cabins, interior fittings and furnishings.

Manufacturing your Yacht

Under the constant supervision of Catamaris ®  and Jean-Jacques Coste, your BLUE COAST 65 catamaran will be built in a certified shipyard in Europe with many years of experience in successfully manufacturing of numerous luxury yachts and multihulls.

Hi All, Can steel make a good materials choice for a small 30' Cat for home building, , and what plus/minus points does 3mm plating pose? http://www.bodenboatplans.com/popup_image.php?pID=23&image=0 http://www.bodenboatplans.com/popup_image.php?pID=23&image=1 BB260 "Steel Catamaran 9 Metre" $595.00 Length 9.0 m Displacement 6500-7500 kg Material Steel Hull Draft 0.85 m LWL 7.9 m Hull Weight 4500 kg steel Beam 3.8 m Max Speed 12 kn Motor capacity 2 x 60 hp Fuel Type Diesel Fuel Capacity 700 litres 100mm x 50 x 3mm cross beams folded plate Fabricated frames 3mm flanged plate. 30 x 3 mm stringers. 2.5 mm superstructure . . A 9 metre steel power catamaran for long distance economical cruising. The alternative way of spacious live a board cruising under power. Also available in aluminium construction and a 4 stroke outboard version in steel or aluminium. An exceptional design. There is nothing else like this seagoing cat on the internet Steel, or steel extended version , also aluminium construction with extended cabin and flybridge Single chine catamaran Hull tunnel to waterline is 300mm loaded and 370mm light Propeller dia 400mm. Fresh water 200 litres. Sewage tank 60 litres. Intended for living aboard for extended periods in the Med. where provisions are available on a weekly basis. This craft was designed so that all nominated fitting out items including tanks etc. were available from the Vertus catalogue, which is readily available world wide. Accommodation is two double berths forward, galley and dinette in wheelhouse saloon. The cockpit is relatively large and is ideal for relaxing outdoors. The shower/toilet space is unusual in that the toiler is located at a lower level on one side and the shower on the starboard side. There is internal entry to each of the machinery spaces with larger maintenance hatched in the cockpit. Sub division with bulkheads make this a very safe boat. The engines shown in the plan are 60hp Dutz as shown in the Vertus catalogue At first we thought that a 9 metre steel catamaran would not be practical. A preliminary design established that providing it was built in 3mm plate,with fabricated frames and tunnel beams,a satisfactory design was possible. The hulls are deep to carry the additional weight and the craft is designed to run at displacement speed with initial estimates indicating a top speed of 14 knots and a very economical cruising speed of 10 knots. Particular attention has been given to the machinery installation with the hull aft designed to accommodate the propellers, reduce draught and enable the catamaran to sit on the bottom. The original craft was designed in 2002 for use cruising the Greek islands. The advantage of steel is that the craft can be built in the open and shot blasted and epoxy painted on completion of the steel fabrication. Click to expand...

Let's see.... The design displacement is roughly four times what a 30' cat should weigh, and the speed is pretty marginal. Setting aside the difficulty in welding steel this thin, you would be far better buying a 30' fiberglass sailing catamaran and adding bigger engines. It would be pretty inefficient compared to a designed power cat, but still far better than this.... Thing.

Actually no difficulty welding this steel thickness with a wire feed machine. Stick welding would be difficult for me, but I am no professional welder. With a quality MIG machine even I could weld very well for a thin steel hull. Cutting the steel with an abrasive wheel is also easy, with virtually no distortion. Steel weight for 3mm thickness is about the same as 35mm plywood, whereas in plywood you could use 20mm thickness. So the hull plating in steel is considerably heavier than with plywood, but most of us know that already. Steel hulls, with a good coating system, can hold up very well, and if that is your preference, then proceed to get what you want.

I doubt if you will get 14 knots with twin 60hp on a 7.5T catamaran. Has someone achieved that speed with one? I recall you have posted before about the powercat you were building. So I am pretty sure you know my Skoota 28, which is, as Stumble says, nearly a quarter the weight of the steel boat. The hulls are 6mm, the decks 9 and 12mm. Yet has proven to be a successful live aboard cruiser. My Skoota 32 is currently being built and will be under 3T in the water If you think that a steel boat will be cheaper remember to add in the cost of bigger engines and the running costs. I suspect the bridgedeck will slam as heavy boats need higher clearance The 9m Catalac doesn't weigh 7T! Richard Woods of Woods Designs www.sailingcatamarans.com

rustybarge said: ↑ My project is to home build a small coastal cruising cat on a small budget. The advantage of steel is easy welding; alloy needs an experienced expert . The materials for a 30' plywood cat come to about $20k using good quality marine ply. Here in Europe steel is at an all time low of £300/ton because of Chinese dumping and oversupply from European mills. I estimate £2k would cover the material costs in steel. Click to expand...

9m Steel Catamaran; thoughts? Click to expand...

waikikin said: ↑ Rustybarge, Steel wins as a low cost start to fabricate, the other materials soon catch up when you factor in abrasive blasting and paint system....welding consumables/gas/ abrasive discs are a minor add on but add up, then you need to build the interior which generally means lining the habitable areas which in effect is building a thin ply/laminate boat inside much of the steel one. It would be one tough little cat, one was for give away incomplete in Wollongong a few years back. At the other end of the project you would have a tough, comfy, slow piece of paradise..... on resale which you may not care about could be very low. Cecil E was a respected designer of commercial craft and some pleasure craft. If he was designing today in the market available that boat might be very different than presented. I'd never say don't build it but keep your eyes wide open at the big pic. Al the best from Jeff. Click to expand...

SamSam said: ↑ It's in your moniker rustybarge...rust. In thin steel, a corrosive pit is halfway through the skin. The worst is from the inside out, from condensation. I imagine creating and maintaining a protective coating in all the nooks and crannies inside those narrow, deep hulls would be a chore. Click to expand...

rustybarge said: ↑ This problem had occurred to me, especially if there are parts of the frames with doublers . how do you stop corrosion once its got into two thin steel plates spot welded together? I suppose after good layer of two pack paint, some sort of wax treatment like waxoil could be injected into overlapping sections of the steel work. But is plywood any better if it gets wet and starts rotting, and how would you dry it out in narrow hard to get at sections? Click to expand...

whitepointer23 Previous Member

what about alloy glued instead of welding. i read somewhere that alloy boats can be glued together just like plywood. i think the bond is also a lot stronger than glued ply bonds. even a combination of epoxy and rivets like an aircraft.

waikikin said: ↑ Well you need to seal weld the perimeter, I'm assuming you're indicating the gussets? lapping the framing. The "secret" with steel or timber for that matter is ventilation and limbering(drainage holes), an effective paint scheme is very important to steel, access to or elimination of void areas as well. The 3K structurally complete cat is fantasy if including coatings even in Pound$. A plywood or composite cabin may be ok if the landing/upstand/coaming is in staino, the fastenings required generally compromise coatings to steel & eventual results blow up with oxygen mixing with steel Jeff.

(Yes, I really am *that* obsessed with Jules and Suzie 😃 after all, they have been sailing for 30 years!)

If you wanted to know:

➜ How Sailing Emerald Steel afforded their boat

➜ How they make their money today

➜ What boat do they have and its upgrades

➜ Who have they also sailed with

➜ How you can start crossing oceans

Then you’ve definitely come to the right place.

Before we start, a quick introduction from me…

The Cruising Freedom Author

Ahoy, Matey! I’m Joshua from Australia.

I’ve built the perfect business to sail the world.

A business model which can allow me to:

➜ Own a catamaran debt-free

➜ Go for weeks without WIFI

➜ Create semi-passive income

But more on that later… 🙂

Sailing Emerald Steel FAQs (April 2023)

S/V Emerald Steel

Crew Members

Julius Hanak (age 73)

Suzie Hanak (age 60)

They built this boat as a custom project more than 30 years ago. It was completed in 1987 and they have owned her since!

They are currently in French Polynesia:

Past Cruising

They have circumnavigated the world more than once.

Affording It

They escaped communism and used a combination of personal savings and ‘sweat equity to build their boat and untie the lines.

Today, Sailing Emerald Steel is worth $220,000 . That appears remarkably small, and yet, they have sustained themselves for so many years.

They ensured they anchored as much as they could, thereby avoiding expensive marinas. Their monthly budget was only around $1,500 combined.

Making Loot

How did they sustain themselves over all these years?

➜ They learned skills they could use in other countries

➜ They did odd jobs along the way to keep going

➜ Today, they make a small income from YouTube

Collaborations

I haven’t seen them on any other cruising channels, but they are similar to Paul and Sheryl Chard and Captain Fatty Goodlander.

You just can’t beat that type of cruising experience.

Big Moments

They have shared some of their worst experiences, including:

➜ Running aground more than once

➜ Partially sinking their boat

➜ Going through extreme weather

They have always kept things real while being conservative sailors and looking for ideal weather windows.

Future Plans

They’re going to keep sailing and aren’t stopping anytime soon!

Key Takeaways

What can we learn from this wonderful couple?

➜ Keep going, no matter the obstacle

➜ Anything is possible with determination

➜ You can keep the same boat for 30+ years

➜ It’s best to have a supportive partner

And of course, learn your own boat work.

Unlike almost every polished channel on YouTube these days, Sailing Emerald Steel aren’t beauty queens and credit card captains.

Instead, they escaped communism many years ago, built their own steel built and went cruising for decades at a time. Today, they’ve earned the respect of the PROPER cruising community, with many of us eager to see what’s to come!

Create Your Own Cruising Freedom

Hey! 😃 it’s Joshua again…

I’m so inspired by Emerald Steel and their 30+ years of travels…

Some say I’m obsessed, but sailing the world is my childhood dream.

They’re living the dream, but that dream isn’t actually that far away.

I mentioned earlier about discovering the #1 cruising business model.

With this exciting opportunity, I’ll be able to:

➜ Generate a sustainable full-time income through learning basic skills

➜ Fund the purchase of my first sailing catamaran without any loans

➜ Do it without selling to friends and family (I found a better solution!)

➜ Share my lifetime passion for sailing, cruising and global adventures

The first group lists our Sailing Yacht Designs and the second group lists our Power Yacht Designs .  Some designs are COMPLETED and others are INCOMPLETE.      COMPLETED STOCK DESIGNS :  The Estimating Plans and Building Plans prices given below in BOLD BLACK TYPE are for a FULLY COMPLETED STOCK DESIGN , the plans for which can be shipped immediately on receipt of your order.   Please see our Stock Design web page for a description of what is included, and how our prices have been determined.    INCOMPLETE OR 'SEMI-STOCK' DESIGNS :   Prices given below in PLAIN TEXT indicate plans that are INCOMPLETE.  WHY , you may ask, have I even bothered to list INCOMPLETE designs below...? Since people's circumstances often change, it is inevitable that some boat design projects will be abandoned before they are finished, and in some cases after considerable work has been done.  This can occur as is so well described in the first few pages of Rockwell Kent’s excellent non-fiction sea story, “North by East” , or as the result of a change of fortune, failing health, or for a myriad of other reasons. A few of the INCOMPLETE designs listed below (not very many) have been developed on my own, in other words, with myself as the 'client'.  Others have been created at the behest of an individual client to explore an idea or a concept.  Either way, I believe all of the designs listed below have merit.  We offer these INCOMPLETE designs at a substantial discount versus what it would cost to develop an entirely CUSTOM design, the difference being that the 'discovery' phase of the design process has already been accomplished.  Even so, there is still quite a bit of WORK REMAINING in order to complete the Plans Packages for those INCOMPLETE designs.  The prices given below reflect our actual cost to complete the Estimating Plans or the Building Plans Package for each design, assuming there will be no changes to the design as it is presented.  If you take umbrage with the cost of our INCOMPLETE designs, I urge you to read our Learning Yacht Design web page.  If one of the designs below is "close" to what you have in mind but you would like to tweak it some, I will be pleased to provide a detailed estimate for any revisions you have in mind.  If any of these designs is of interest, please inquire .    CUSTOM YACHT DESIGN :  A new CUSTOM design will necessarily include the process of " discovery " which represents Stage I of the design process, during which all options are on the table including size, type, configuration, layout, rig, materials, etc.  By comparison, given that many of the INCOMPLETE designs listed below have already had a considerable amount of design work done, very roughly the cost to create a CUSTOM design can be on the order of some 20% to 50% greater than the prices listed for the INCOMPLETE designs below, in order to accommodate the "discovery" process on the way to achieving a completed set of Building Plans.  Is the added cost worth it...?   Yes , we believe so. Please see our article on Custom Yacht Design for our best answer to that question, where you will also find an overview of the design process itself.  Our Design Stream article additionally describes how we use CAD to best advantage throughout the design process. If a new Custom Yacht Design is of interest, please inquire for more information.    COMPLETED NC CUTTING FILES :  There are several designs below for which NC Cutting files are ALREADY DEVELOPED , in which case the price is in BOLD BLACK TYPE .    DEVELOPING NEW NC CUTTING FILES :  All other NC Cutting File prices are listed in PLAIN TEXT, and reflect our actual cost to develop NC Cutting Files for that design from scratch, in which case they can be developed for metric or imperial dimensioned materials as needed. Please see our CAD Design Stream article for more information about our NC development process.    ORDERING INFORMATION : All prices are given in US Dollars and are subject to change at any time.  To place an order, please see our contact information below. To order by fax or by mail, a PDF Order Form has been provided for your convenience.    What's Included...? Estimating Plans - Building Plans - NC Cut Files... ESTIMATING PLANS :  Since all the basic information about each of our designs is available here at our web site, and for free, we no longer offer basic Study Plans.   Instead, we offer a much more useful and complete Estimating Plans for each of the designs listed below. Our Estimating Plans include the following: Drawings:    Sail Plan / Exterior Profile Drawing Interior Profile & Arrangement Drawing (one to four sheets, depending on vessel size) Structure Drawings (one or two additional sheets, depending on vessel size)    Documents:    Drawings & Documents List Written Vessel Specification Detailed Equipment List Structural Scantling List Laminate Schedule (if needed) Structure Weight & Surface Areas Builder Short List appropriate to the specific design Cover Letters to Builders re: scope of project, etc.    Our Estimating Plans are useful for study, planning, commentary, or mark-ups in the event you want to consider variations on the layout or the rig.  Primarily though, the Estimating Plans are intended for Cost Estimating .   Considering the price lists given below, the Estimating Plans represent an outstanding bargain and include quite a lot of useful information. Our Designer's Cover Letter serves as an introduction to the builder and outlines the scope of our involvement.  Our Owner's Cover Letter is a template which you can modify as needed in order to provide an introduction to the builder; to outline your intended build timing; and to let them know what stage of completion you intend their quotation to cover. NOTE :  Estimating Plans do not contain sufficient detail for actual construction of the vessel.  However the Estimating Plans do provide enough information so that builders can provide a firm quotation for construction, and to allow a preliminary construction contract to be negotiated.    BUILDING PLANS : Prior to your construction contract being finalized, and in order to actually build the boat, the complete Building Plans will be required.  Our Building Plans include all the contents of our Estimating Plans as listed above, plus all the remaining detail drawings required for construction, including the following: Drawings:    Lines Drawing Offsets (if not CNC cut) Structural Sections Joinery Sections Joinery Details Construction Details (Several Sheets Including Hull & Deck Fittings; Ports; Doors; etc.) Spar Plans (Sail: Several Sheets Including Spar Dimensions; Spar Fitting Details; etc.) Machinery Plans (Power:  Several Sheets as Needed) Numerous Detail Drawings as Needed       Vessel Design Data, including:    Hydrostatics & Trim Stability Compliance Report Performance Analysis Hull Data for Propeller Calcs Endurance & Range Under Power    Building Plans also include a thorough review of and revision of the Equipment List and Vessel Specification in order to suit your specific equipment preferences. If the drawings or documents require further revision for your use, for example to make changes to the layout or the rig, we'll be pleased to provide an estimate for making those revisions. Please see our Stock Plans page for more information about what's included, and how we can customize a stock design to suit your requests.    CUSTOM DESIGN : We can modify any of our Stock Designs to suit a newly defined purpose, or we can work with you to create an entirely new design based on your requests. Please feel free to inquire about any modifications you may have in mind, or about creating a new Custom Design to suit your specific requirements.  In way of inspiration we have provided quite a variety of Prototype Designs , any one of which can be modified as needed to create a fully completed yacht design.    NC CUTTING FILES : Several of the Stock Designs listed below for construction in metal have already been developed for automated NC cutting of the metal parts. "NC" simply means 'Numerically Controlled' - a technology for creating pre-cut boat parts directly from the 3D design model. For details regarding the benefits of NC Cutting and to find out what's included with an NC Cutting File Package , check out our article on Our CAD Design Stream and the articles linked from there.    MORE INFO :  Please see our Site Map to quickly find any of our designs, to peruse our portfolio, and to find our articles on a variety of boat related topics.  

What Will the Boat Cost..?

This is the most difficult question of all, and one for which I do not have a ready answer.  However it is a question that ultimately does have an answer...!   For any meaningful cost discovery it is necessary to solicit actual quotations for construction from a short list of qualified builders. 

For that purpose, we offer completed ESTIMATING PLANS for several of the designs listed below, with their prices listed in BOLD BLACK TEXT .  For any designs listed below that are INCOMPLETE, we have also provided the cost to develop ESTIMATING PLANS for that design, the prices for which are given in PLAIN TEXT.

Please see the following articles for information about boat costs, and about the process of soliciting estimates from builders:

IMPORTANT DESIGN NOTES

GRP or PLYWOOD : Any of our Aluminum or Steel designs can be converted for construction in GRP or cold moulded plywood. The cost of any such revisions will be quoted separately. For more information, please inquire .

STEEL : Any Steel vessel can easily be re-specified with an aluminum structure. To convert a stock steel design to aluminum, please add 20% to the cost of the Estimating Plans or the Building Plans for that design.  Conversion of NC Cutting Files from steel to aluminum will however require a completely new set of NC cutting files, for which please inquire for an estimate.

* ALUMINUM : The Aluminum vessels listed above can only be built in steel if the design is extensively modified for that purpose in order to accommodate the added weight of the structure. For more information, please inquire .  Conversion from aluminum to steel will also require a completely new set of NC cutting files, for which please inquire for an estimate.

** WOOD : Please note that our large Wooden Vessel plans are generally priced higher, since revisions will nearly always be required in order to accommodate the differing wood species that will be available for construction, and the consequent differences in scantlings and overall weight. Those revisions (within reason) are included in the prices indicated above.

*** NC CUTTING FILES : Although a complete Building Plans set is required in order build any of these boat designs, the NC Cutting Files are entirely optional . In other words, the Building Plans are required , even if you purchase the NC Cutting Files for that design. The cost of NC Cutting Files is in addition to the cost of the Building Plans. Please see above for discount options that are available...

The NC Cutting Files shown above with prices given in BOLD BLACK TYPE have already been developed , in which case they will have been created for either metric or imperial dimensioned materials, and for either steel or aluminum (noted in parentheses).

If the vessel will be built in a location that requires changing the measurement system , and / or if there is a change from steel to aluminum or aluminum to stee l structure, then additional work will be required, the cost of which will be quoted separately and in addition to the above prices. Should such changes to any of our designs be of interest, please inquire for an estimate.   

YACHT TENDERS

Our aluminum yacht tenders are the perfect companion to any of the yachts described above.

8' to 14' Prams - Building Plans: $250 . NC Cutting Files: $250 . (The Building Plans are required. The NC Cutting File is optional. The cost of the NC Cutting file includes interacting with the cutter of your choice to assure compliance with their cutting equipment.)  

PROTOTYPE YACHT PLANS

If you don't see a design here that suits your requirements, please see our Prototypes web page for links to other designs that are either under development, or that may offer a few possible ideas in way of inspiration...

Preliminary study sketches may be available for some of our Prototype Designs. If you would like to know more about one of them, please inquire .  

NACA Foil Shaped Low Drag Aluminum Paravanes

Please see our Roll Attenuation article for more information on Paravanes for Motor Yachts.

These low-drag paravanes are balanced and are adjustable for different speeds. They make use of NACA foil shaped surfaces combined with a lead ballasted NACA foil shaped bulb. They are designed to be machined out of marine grade aluminum plate and rod so that they can be shaped, and so they are lighter for a given wing area than steel paravanes would be.

The sizes given above are conservatively rated. In other words each size can be used on a larger vessel than is indicated. It is all a matter of degree. The roll attenuation will simply be more or it will be less, as compared to that of a larger or smaller wing area.

Paravane effectiveness is a function of wing area and pole length vs. your vessel’s righting moment. With a larger the vessel the poles can be made longer, achieving greater leverage, therefore a greater effect for the same size paravane.  If you have an existing vessel on which you would like to install these paravanes, but you don't have a paravane rig, we can provide a design for the rig that will fit your boat.

For more information, please inquire .

The ZEN50 is a game changer. World’s first series production catamaran equipped with a wingsail, it defines a new distinctive class of its own, where genuine zero-emission meets high comfort and performance, limitlessly. 

Designed from scratch for ZEN Yachts by award-winning naval architect Julien Mélot , this full carbon catamaran is the ultimate essence of technology driven, high performance and luxurious, eco-friendly leisure yachting. 

The blue water capable ZEN50 lightweight racing carbon hulls are combined with a huge solar roof for an unrivaled solar power vs. displacement ratio above 1:1 (18 kW / 17 tonnes), making this yacht completely energy self-sufficient. A revolutionary, fully automated, wingsail - by Ayro© - can be added as a range and speed extender. The yacht’s high capacity battery bank powers a powerful silent electric propulsion, allowing the ZEN50 to achieve 14 knots and maintain high continuous speeds in unrivaled safety and comfort, indefinitely… 

The ZEN50 is offered with or without wingsail and comes in 3 main different versions: Racer, Cruiser and Explorer, each dedicated to a different usage and owner profile. We use these versions as a basis to define a final, bespoke specification for each of our valued clients and ZEN Community Members. Scroll down for more details, specifications and prices.

1st WINGSAIL series production yacht in the world!

The OceanWings32 - by Ayro© - was initially developed for Team Oracle, for the America’s Cup 2010 in Valencia. Over years, it has further been developed and automated by VPLP and was installed on Energy Observer in 2019. Two years of field feedback have allowed the Ayro team to fine tune the algorithm commanding the wingsail. The ZEN50 is the first series production leisure craft to be equipped with this fully automated wingsail. It is controlled at the touch of a finger on screens, is automatically adjusted and has several safety modes and features. The two parts of the wingsail can be hoisted and lowered independently and with the simple touch of a button. The wingsail OceanWings32 is the ideal complement for the solar roof for those wishing to cruise long distances off-shore with zero-emissions.

Greatest ratio SOLAR POWER / weight on the market

At 17 tonnes lightweight and 18,000 W of peak solar power, the ratio of the ZEN50 is at over 1 kW per displaced tonne of water or beyond 1:1 which is far beyond any other blue water CE Cat A yacht in this size range. Lots of solar power for little water to displace is the strong and healthy foundation the energy self-sufficient ZEN50 is built upon.

Performance CARBON sandwich hulls

The hulls of the ZEN50 have been designed from a blank screen for ultimate efficiency - understand minimum drag or minimal energy consumption for a range of speeds from 6 to 10 knots. Their shape is aggressive, sharp and slender. Their reverse bows cut through water like a sword cuts through butter and their curvature is reminiscent of graceful dolphin bodies. These hulls are undoubtedly of the performance type and are built with the best available composites: Carbon fibre and Corecell™. The combination of high strength, low weight and performance design allow the ZEN50 to reach speeds of up to 14 knots.

INFINITE range at high CONTINUOUS speeds

With maximized solar and wind power and minimized energy consumption… the ZEN50 can sail continuously at speeds varying between 6 and 10 knots. Thorough simulations in various sea states and weather system have consistently shown the ZEN50 will be able to achieve performance catamaran speeds continuously without using a genset. With the ZEN50, the world is your oyster and the wildest destinations are within your reach with this self-reliant vessel!

True ZERO-EMISSION operation

The first ZEN50 unit, whose construction started in March 2023, will not be equipped with a genset at all and will not have any fossil fuels onboard. The ZEN50 energy system with its very large capacity 160 kWh battery bank, has been designed to function for days in complete safety with minimal solar energy harvest and no wind. It is perfectly safe with no backup genset and operates 24/7 without any polluting emissions.

NO FUEL , no costs

Naturally, requiring no fuel to operate day in day out is great news for the environment, it is also fantastic news when sailing into remote areas where fuel bunkering might be near impossible or where the fuel quality might be an issue. Finally, it also makes a massive difference in this yacht’s costs of operation. Imagine the hundreds of liters of diesel saved over just a week, the obsolete engine maintenance schedules, the clogged filters and dirty tanks from another age… Welcome to a new burden-free, energy self-sufficient era, welcome to clean and graceful eco-yachting, welcome to ZEN Yachts.

Highest SAFETY & reliability

At ZEN Yachts, we have made some design choices to attain energy self-reliance with the ZEN50 that reduces the habitable volume in the hulls, similar to performance catamarans. Where we have not and will never compromise is on safety. Our main voltage system is 48V making it perfectly safe to work on. The level of redundancy of the batteries and solar panels is 10! The main electrical architecture is split in 2 so that should anything happen on 1 hull, the entire vessel can still operate normally. There are 2 independent helm stations and the ZEN50 is packed with special safety features, nonsubmersible compartments and we can even offer an in-depth practical course on safety equipment usage and management. Sailing with the ZEN50 is not only exhilarating and clean, it is ultra safe!

Unrivaled space & COMFORT

The ZEN50 offers the speeds of a performance catamaran, the comfort of a large motor yacht and the simplicity of an electric car. No less than 2 large day beds, 3 dining areas for over 10 people, 1 professional galley and 2 wet kitchens, 5 heads, up to 4 double ensuite cabins, 1 bunk double and 1 single together with both saloon and dining areas converting into extra sleeping areas, this is simply unrivaled on a 50 ft. catamaran. Add an electric tender, dive compressor, satellite internet, 2 helm stations (cockpit and flybridge), a solar roof that converts into a gigantic upper deck to enjoy the most epic sunrises and sunsets, welcome onboard the ZEN50!

No, is the short answer. It's just too heavy. A typical 10m catamaran might be built in 9mm ply. This weighs about 1lb/sqft. In comparison, 4mm steel plate - the thinnest you can use for boatbuilding, weighs about 7.5lbs/sqft! Clearly a boat built in steel will be far too heavy for any normal boat. However, some large catamarans (say over 45') have been successfully built in aluminium.

Having said that, most people want a wood interior while condensation is a problem on all metal boats. Thus significant extra non structural weight is added to the shell which compounds the problem. Also don't forget that the cost of the hull shell is only about 30% of the total cost, so any material savings will only have a small impact on the total budget.

The Ultimate Guide to Choosing Between a Sailboat or Catamaran for Your Sailing Adventures

C hoosing between a sailboat and a catamaran for your sailing adventures is a significant decision that depends on various factors, including your sailing preferences, experience level, budget, and intended use. Here's an ultimate guide to help you make an informed decision:

1. Sailing Experience:

• Sailboats: Typically require more skill and experience to handle, especially in adverse weather conditions. Ideal for sailors who enjoy the traditional feel of sailing and are willing to invest time in learning and mastering the art.
• Catamarans: Easier to handle, making them suitable for beginners. The dual-hull design provides stability, reducing the learning curve for those new to sailing.

2. Space and Comfort:

• Sailboats: Generally have a narrower beam and less living space. However, some sailboats may offer comfortable cabins and amenities.
• Catamarans: Wider beam creates more living space. Catamarans often have multiple cabins, spacious saloons, and expansive deck areas, providing a more comfortable living experience.

3. Stability:

• Sailboats: Monohulls can heel (lean) while sailing, which some sailors enjoy for the thrill but can be discomforting for others.
• Catamarans: Greater stability due to the dual hulls, providing a more level sailing experience. Reduced heeling makes catamarans suitable for those prone to seasickness.

4. Performance:

• Sailboats: Known for their upwind performance and ability to sail close to the wind. Some sailors appreciate the challenge of optimizing sail trim for efficiency.
• Catamarans: Faster on a reach and downwind due to their wide beam. However, they may not point as high into the wind as monohulls.
• Sailboats: Typically have a deeper draft, limiting access to shallow anchorages and requiring deeper marina berths.
• Catamarans: Shallow draft allows access to shallower waters and secluded anchorages, providing more flexibility in cruising destinations.
• Sailboats: Generally more affordable upfront, with a wide range of options available to fit different budgets.
• Catamarans: Often more expensive upfront due to their size and design. However, maintenance costs may be comparable or even lower in some cases.

7. Mooring and Docking:

• Sailboats: Easier to find slips and moorings in marinas designed for monohulls.
• Catamarans: Require wider slips and may have limited availability in certain marinas, especially in crowded anchorages.

8. Intended Use:

• Sailboats: Ideal for traditional sailors who enjoy the art of sailing, racing enthusiasts, or those on a tighter budget.
• Catamarans: Suited for those prioritizing comfort, stability, and spacious living areas, especially for long-term cruising and chartering.

9. Resale Value:

• Sailboats: Generally have a more established resale market, with a wider range of buyers.
• Catamarans: Growing in popularity, and well-maintained catamarans often retain their value.

10. Personal Preference:

• Consider your personal preferences, the type of sailing you plan to do, and the kind of lifestyle you want aboard your vessel.

In conclusion, both sailboats and catamarans have their advantages and disadvantages. Your decision should be based on your individual preferences, experience level, budget, and intended use. If possible, charter both types of vessels to experience firsthand how they handle and to help make a more informed decision based on your own preferences and needs.

Cruising the Moskva River: A short guide to boat trips in Russia’s capital

There’s hardly a better way to absorb Moscow’s atmosphere than on a ship sailing up and down the Moskva River. While complicated ticketing, loud music and chilling winds might dampen the anticipated fun, this checklist will help you to enjoy the scenic views and not fall into common tourist traps.

How to find the right boat?

There are plenty of boats and selecting the right one might be challenging. The size of the boat should be your main criteria.

Plenty of small boats cruise the Moskva River, and the most vivid one is this yellow Lay’s-branded boat. Everyone who has ever visited Moscow probably has seen it.

This option might leave a passenger disembarking partially deaf as the merciless Russian pop music blasts onboard. A free spirit, however, will find partying on such a vessel to be an unforgettable and authentic experience that’s almost a metaphor for life in modern Russia: too loud, and sometimes too welcoming. Tickets start at $13 (800 rubles) per person.

Bigger boats offer smoother sailing and tend to attract foreign visitors because of their distinct Soviet aura. Indeed, many of the older vessels must have seen better days. They are still afloat, however, and getting aboard is a unique ‘cultural’ experience. Sometimes the crew might offer lunch or dinner to passengers, but this option must be purchased with the ticket. Here is one such  option  offering dinner for $24 (1,490 rubles).

If you want to travel in style, consider Flotilla Radisson. These large, modern vessels are quite posh, with a cozy restaurant and an attentive crew at your service. Even though the selection of wines and food is modest, these vessels are still much better than other boats.

Surprisingly, the luxurious boats are priced rather modestly, and a single ticket goes for $17-$32 (1,100-2,000 rubles); also expect a reasonable restaurant bill on top.

How to buy tickets?

Women holding photos of ships promise huge discounts to “the young and beautiful,” and give personal invitations for river tours. They sound and look nice, but there’s a small catch: their ticket prices are usually more than those purchased online.

“We bought tickets from street hawkers for 900 rubles each, only to later discover that the other passengers bought their tickets twice as cheap!”  wrote  (in Russian) a disappointed Rostislav on a travel company website.

Nevertheless, buying from street hawkers has one considerable advantage: they personally escort you to the vessel so that you don’t waste time looking for the boat on your own.

Prices start at $13 (800 rubles) for one ride, and for an additional $6.5 (400 rubles) you can purchase an unlimited number of tours on the same boat on any given day.

Flotilla Radisson has official ticket offices at Gorky Park and Hotel Ukraine, but they’re often sold out.

Buying online is an option that might save some cash. Websites such as  this   offer considerable discounts for tickets sold online. On a busy Friday night an online purchase might be the only chance to get a ticket on a Flotilla Radisson boat.

This  website  (in Russian) offers multiple options for short river cruises in and around the city center, including offbeat options such as ‘disco cruises’ and ‘children cruises.’ This other  website  sells tickets online, but doesn’t have an English version. The interface is intuitive, however.

Buying tickets online has its bad points, however. The most common is confusing which pier you should go to and missing your river tour.

“I once bought tickets online to save with the discount that the website offered,” said Igor Shvarkin from Moscow. “The pier was initially marked as ‘Park Kultury,’ but when I arrived it wasn’t easy to find my boat because there were too many there. My guests had to walk a considerable distance before I finally found the vessel that accepted my tickets purchased online,” said the man.

There are two main boarding piers in the city center:  Hotel Ukraine  and  Park Kultury . Always take note of your particular berth when buying tickets online.

Where to sit onboard?

Even on a warm day, the headwind might be chilly for passengers on deck. Make sure you have warm clothes, or that the crew has blankets ready upon request.

The glass-encased hold makes the tour much more comfortable, but not at the expense of having an enjoyable experience.

Getting off the boat requires preparation as well. Ideally, you should be able to disembark on any pier along the way. In reality, passengers never know where the boat’s captain will make the next stop. Street hawkers often tell passengers in advance where they’ll be able to disembark. If you buy tickets online then you’ll have to research it yourself.

There’s a chance that the captain won’t make any stops at all and will take you back to where the tour began, which is the case with Flotilla Radisson. The safest option is to automatically expect that you’ll return to the pier where you started.

Ukraine war latest: Putin arrives in North Korea; Russian forces 'move closer to key supply route'

Vladimir Putin has arrived in North Korea for a two-day visit - his first in more than two decades. Elsewhere, the UK's Ministry of Defence says Russian forces are moving closer to a key Ukrainian supply route in the eastern Donetsk region.

That's all of our live coverage on the conflict for now. 

We'll bring you any major developments overnight, and we'll be back with our regular updates in the morning. 

More details about Vladimir Putin's arrival in North Korea have started coming through...

The Russian president arrived in the country for the first time in 24 years earlier this evening, and was greeted by North Korean leader Kim Jong Un. 

The two men had a brief conversation and then left Pyongyang Airport in the same car. 

Now, Korean Central News Agency has reported that the pair shared their "pent up inmost thoughts" with each other and "opened their minds". 

The North Korean state news organisation said the conversation was "friendly" and came as their relationship "entered a course of new comprehensive development". 

It added that Putin's visit was important in "powerfully propelling the cause of building a powerful country". 

Of course, the Korean Central News Agency's original reporting is in Korean, so there may be some discrepancies in the translation. 

The destruction of Russian targets in border regions "really matters", Volodymyr Zelenskyy has said as he praised world leaders for their determination to protect Ukraine, 

Delivering his nightly address, the Ukrainian president said: "The destruction of Russian terrorists' positions and launchers by our forces, our warriors, near the border really matters. 

"We witness the world's determination opening new prospects for restoring our security. Among other things, this includes the security of Kharkiv." 

His comments come after Ukraine claimed responsibility for an overnight drone attack on a Russian oil facility. 

The strike caused a massive blaze in Russia's Rostov region and marked the latest long-range attack by Kyiv's forces on a border region.

Ukraine has in recent months stepped up aerial assaults on Russian soil, targeting refineries and oil terminals, in an effort to slow down the Kremlin's war effort. 

At the same time, Moscow's army has been pressing hard along the front line in eastern Ukraine, where a shortage of troops and ammunition has made defenders vulnerable.

As we have been reporting this evening, Vladimir Putin has arrived in North Korea for the first time in 24 years to begin a two-day visit. 

The Russian president was greeted by North Korea's leader Kim Jong Un, with the men seen laughing and hugging as they had a conversation near Putin's plane.

A red carpet was rolled out for his arrival as well. 

The US has said it is concerned about the "deepening" cooperation between Russia and the North Korea.

The Pentagon voiced concern about the growing ties between Moscow and Pyongyang as Vladimir Putin arrived in North Korea for his first visit in 24 years. 

"The deepening cooperation between Russia and the DPRK is something that should be of concern, especially to anyone that's interested in maintaining peace and stability on the Korean Peninsula," Major General Patrick Ryder, a Pentagon spokesperson, told reporters.

DPRK is an abbreviation for North Korea's official name, the Democratic People's Republic of Korea. 

We have just received the first photos of Vladimir Putin arriving in North Korea. 

The Russian president was greeted by the country's leader Kim Jong Un as he left his plane. 

The pair hugged and had a brief conversation before leaving in the same car. 

We are starting to get more details about Vladimir Putin's arrival in North Korea. 

As the Russian president touched down, he was greeted by the country's leader Kim Jong Un. 

The two men had a brief conversation next to Putin's motorcade, before leaving Pyongyang Airport in the same car.

As we told you in our last post, Vladimir Putin has arrived in North Korea for his first visit in 24 years. 

The Russian president's plane touched down in Pyongyang around 2.45am local time (6.45pm UK time) after a stopover in Russia's far east. 

He was reportedly greeted by North Korea's leader Kim Jong Un. 

Here's a quick look at what is expected to take place during his two-day visit...

One of the first events to take place will be one-on-one discussions between the two leaders. 

There will also be a gala concert, state reception, honour guards, document signings, and a statement to the media, Russia's Interfax news agency quoted Mr Putin's aide as saying.

A number of Russian officials have travelled to Pyongyang as well as part of Mr Putin's delegation, including defence minister Andrei Belousov, foreign minister Sergei Lavrov and deputy prime minister Alexander Novak. 

Ahead of the visit, North Korea appeared to make preparations for a possible military parade in downtown Pyongyang. 

Vladimir Putin has arrived in North Korea, the Kremlin has confirmed. 

The Russian president touched down in the country's capital, Pyongyang, where he will begin his two-day visit.

He was greeted at the airport by North Korea's leader Kim Jong Un, according to RIA Novosti. 

A formal meeting between the two leaders is expected to take place tomorrow. 

In a presidential order issued yesterday, Putin said Moscow was looking to sign a "comprehensive strategic partnership treaty" with North Korea. 

The international community has raised alarm bells regarding his trip, with NATO secretary-general Jens Stoltenberg saying the military alliance was concerned about the support Russia could provide for North Korea's missile and nuclear programmes. 

Three Russian government aircraft have landed in Pyongyang in North Korea, according to flight tracking data. 

It is unclear if Vladimir Putin is on board any of the planes, but their arrival comes as the Russian president is expected to visit the country.

Flight Radar 24 shows the planes travelled from Yakutsk in east Siberia, where Putin travelled to earlier today.
