Tiki 30 Catamaran: A Practical Sailor Boat Test
This wharram-designed coastal-cruising cat is a tempting diy boatbuilding project for those looking to get back to the basics..

Photos by Ralph Naranjo
Part of the catamaran designer James Wharrams success story lies in the lifestyle he has been marketing along with his boats. For decades, like fellow cat-cult heroes Arthur Piver and Jim Brown, he has launched people as well as boats on voyages of discovery. He pitches the case for Spartan simplicity and self-reliance and backs it up with a forthright and savvy boatbuilding syllabus. His is the anathema of the ferro-cement craze, more of a “do with less” rather than “load her up” mindset. He sells his ideas as effectively as any self-help telemarketer, and his elixir to cure a mundane life ashore makes much more sense.
Those who drop in on Wharrams website www.wharram.com are encouraged to buy a pithy, 72-page book thats an unabashed advertisement for Wharrams boats, the practicality of his approach, and the need to shrug off shoreside claptrap and clutter when going to sea. This diehard pitch in support of adventure is infectious, and Wharram spells out how a handy, but not professionally trained, do-it-yourselfer can succeed with his designs.
The semi-hooked can order “study plans” of one or more of the Wharram lines, and the subject of this review-the Tiki 30-is part of the Coastal Trek series. These study plans afford greater specific detail about Wharram designs and spell out the materials needed. They also lead you through a materials tally that includes details about epoxy resin, plywood types, sails, hardware, lines, an outboard auxiliary, and other bits and pieces.
Once you have figured out where you can come up with an average of 900 hours of free time-Wharrams DIY labor estimate-you may be close to plunking down $1,000 for detailed building plans. Those who take the leap and create their boat from scratch say it was worth the investment. Those who also complete the voyage they dreamed about have even more good things to say about the “Wharram Way.”
“Living on the sea” is one of Wharrams favorite phrases, and in many ways, hes as much a cruising enabler as he is a boat designer. Like Brown, and his lure of “Seasteading,” Wharram dangles a mostly realistic getaway plan in front of potential clients. The price point is attractive, at least as long as one views the labor commitment as part of the recreational experience. But when all the glue and paint has finally cured, the bottom line is that the Tiki 30, and most of the other Wharram cats, are best suited to cruisers willing to slip away without huge battery banks, large-volume water tanks, and with less mechanical propulsion reliance. Theres little sense in fitting granite countertops and aiming for a monohull-like interior in the limited space available aboard these catamarans.
One Particular Tiki
Occasionally, we take a close look at a non-mainstream vessel, believing that the old adage “one size fits all” has less merit among sailors. And near the top of our “cult following” list of sailboats are the Wharram-designed fleet of catamarans that are built by dedicated do-it-yourselfers as well as professionals. When we heard that voyager/boatbuilder Dave Martin had just finished a Wharram Tiki 30, we knew that the timing was right for a look at a unique vessel, its crew, and the designer.
A Rare breed
Dave and Jaja Martin and their three children are among the rarest breed of family cruisers, a couple who have sailed and savored the razor-thin edge between high risk and even higher reward. Twenty-plus years ago, when Dave sailed off in his completely restructured and highly modified Cal 25 Direction , he found that single-handing held little appeal. So, after an Atlantic crossing and a Caribbean wedding, he and Jaja followed the tradewind route around the world. The singlehander was now part of a family of five that had outgrown their pocket cruiser. So with a Cal 25 circumnavigation astern, thoughts of a next boat began to take shape.
The curtain lifted on the second act with the Martins rebuilding a 20-year-old, 33-foot steel sloop, literally tearing out the interior and starting from scratch. After an 18-month refit, there came an Arctic adventure that would carry Driver and its crew to Iceland, Norway, Greenland, Newfoundland, and the experience of living aboard during winters in which the rolling sea became as solid as granite. The Martins exemplify voyaging tenacity, but they earn even higher marks for their self-reliance. Theres no sponsorships for their adventures, or independent wealth to fuel a whim. They have taken very modest vessels and turned them into passage-making vehicles able to handle the task at hand. They worked their way around the world and met the locals as participants in their culture rather than as spectators.
Having first met Dave in the Bahamas in 1984 and coaxed him to come work in a boatyard that Practical Sailor Technical Editor Ralph Naranjo was running on Long Island Sound, Naranjo had the good fortune of seeing how seafaring goals and a shipwrights set of skills can set the stage for special cruising opportunities.
![wharram catamaran trailer Tiki 30 Catamaran](https://cdn.practical-sailor.com/wp-content/uploads/2020/03/1110-tiki30RJN_0102-copy.jpg.webp)
except where noted
Act 3 in the Martin saga is like a symphony with a major change in cadence. This time, priorities such as heavy weather survivability, high-volume stowage capacity, and ice resistance were off the drawing board. In their place came priorities such as simplicity and sailing efficiency, along with the imperative that this will be a “from scratch” Dave-built boat. No mean feat in itself, this boat-building endeavor was all the more impressive because the top of the “honey-do list” was a cottage to live in, a shop to work from, and the building of Dave and Jajas dream house. For most of us, this would relegate the boat project to pipedream status, a project that would likely never be started. But for the Martins, in just over a half-dozen years, the trifecta was complete.
The tide has turned, and their family life proceeds with a shoreside cadence. Adolescents are becoming young adults, and the Maine woods rather than a blue horizon dominate the picture. But true to form, as soon as the house was finished, the table saw gathered no rust. Nor did the other tools in the woodshop, as Dave began cutting carefully scribed curves on Okume plywood. One-at-a-time the amas for a 30-foot Tiki filled the extended garage boat shop. The choice of a double- hulled canoe catamaran doesn’t surprise anyone who knows Dave and Jaja. As sailing adventurers, they have yet to sing the same song twice.
Gravitating toward a new mode of cruising, they embraced the theme of light displacement, efficiency under sail, and simplicity. Spartan minimalism is the common thread in this and the other boats of the Martins two exemplary voyages. The elegance in each of these vessels has little to do with opulence, and everything to do with how the boats have fit the job at hand. Simplicity, functionality, and cost effectiveness abound, defining the approach Dave brings to boatbuilding. He still alludes to a down-the-road, larger monohull project for more oceanic adventure, but for now, its all about quick getaways, coastal cruises, light-air sailing, and shoal-draft exploration.
Design Details
The Wharram Tiki design was a natural choice for Dave because the designer has always approached his work from a builder/sailor perspective, rather than as an independent exercise in naval architecture. Simplicity and practicality rule, and in many ways these boats are the extreme opposite of whats displayed at boat shows across the country. Instead of a living room afloat, the Tiki 30 offers wood-grained camp-style accommodations that are enough for a weekend outing, or two-week summer cruises for hardy souls, but will hold little appeal to those looking for a vacation home afloat.
The real genius in this boat comes more from whats not present than whats found on board. No lead, no liners, and no inboard engine adds up to, or more specifically diminishes down to, a displacement that is so light that a low-tech, no-boom small sail plan can provide enough drive to make way, even when the sea surface is mirror smooth. In light zephyrs, this agile cat will tack and make progress to windward. Behaving like a waterbug skittering across the water, the boat reminds the person handling the butter-smooth tiller bar how important efficiency under sail can be.
Like all multihulls, the issue of initial stability is handled by placing the source of buoyancy well away from the centerline of the vessel without creating the skin drag found in a monohull with massive beam. The combination of a high length-to-beam ratio associated with each ama, and ultralight displacement, the Tiki 30 is a thoroughbred when it comes to efficiency and agility.
![wharram catamaran trailer Tiki 30 Catamaran](https://cdn.practical-sailor.com/wp-content/uploads/2020/03/1110-boat-review.jpg.webp)
Thanks to this ultralight displacement status, the Tiki doesn’t need a cloud of sail to deliver light-air efficiency, and Wharram further reduces the need for a tall spar by leveraging aspect ratio through the use of a simple gaff-rigged mainsail. On one hand, the complication of hoisting both a peak and throat halyard adds some extra complexity, but the result is a higher center of effort (CE) with a lower masthead height, and when it comes to building a simple timber spar, it all makes sense. Yes, a carbon spar and PBO rigging would do a better job, but the cost would be more than a DIY builder spends on all of the materials used to build the rest of the boat.
Every multihull designer is concerned about racking or twisting loads induced in a structure as the heeling force and righting moment interplay on rolling sea. Some use massive bridgedeck structures to transfer rig loads from ama to ama. The Tiki 30 incorporates three well-engineered triangular beam structures and a modern rendition of the Polynesian art of lashing canoe hulls together. Care must be taken during construction to make sure that each beam has a flush fit with a well-reinforced portion of the ama deck, and that the polyester double-braid line used for the lashing is tensioned to designer specifications. These rigidly held athwartship supports may creak in a rolling seaway, but the connection between hulls is rugged and long lasting.
Performance
Under sail, the Tiki is an agile and responsive performer. It balances well, and its V-shaped sections and long shallow keel plus outboard rudders provide good directional stability and responsive steering. The underbody configuration allows the cat to be safely beached, and the complexity of dagger boards is eliminated. The lack of daggerboards has its drawback: Theres less windward capability, but the V-shaped hulls and long run of shallow keel does pretty well to windward without them.
Perhaps the most rigid design characteristic that can’t be circumvented is the importance of keeping its payload in check. This is a boat designed to stay on its lines not bog down and suffer the consequences of excess drag. Its long, lean amas knife through the sea, but their ability to put up with excess weight is minimal. More weight necessitates additional buoyancy, and as the V-shaped sections are submerged, significant increases in skin drag occur along with a loss of vital freeboard. This runs contrary to the design attributes of the vessel and results in performance setbacks and poor sea-keeping ability.
These fast, nimble, cost-effective cats garner a following among do-it-yourself builders because they are efficient to build. Wharrams streamlined approach to construction is a comprehensive blend of materials and hull-shape development that results in a strong, light structure. The expedited build process is free of finicky labor-intensive work and costly esoteric materials. In essence, Wharrams approach uses a minimal strong back, a stitch-and-glue joining process, and lines that allow large scarf-joined panels of high-quality marine plywood to be bent into the shape of a double-canoe catamaran. Bulkheads act as the athwartship formers, and as Wharram puts it, the builder uses a thickened epoxy filleting compound to “weld” the wood together.
The Tiki 30 is well-tailored for Spartan coastal cruising but a bit gossamer for ocean passagemaking, despite the fact that many have done so. Its ability to tuck into tight places, to perform admirably under power with only a 9.9-horsepower long-shaft, four-stroke kicker and its ability under sail give it high marks in our book. For many, camper/cruiser comfort is enough, and with the easy unfurling of a full cockpit awning, the boat becomes spacious enough at anchor to fulfill the dreams of a vacation cruise.
The Tiki is indeed a versatile platform, a pleasure to sail, and a project worth tackling if youre not too worried about dollars and cents. Wharram boats backyard-built pedigrees and their fringe appeal make them a tough sell on the used boat market, so if you plan to build one, you had better plan to sail it.

Projects: Building the ultimate ‘trailer sailer’ with epoxy
Celebrating sixty years since he first journeyed across the Atlantic in his self-built catamaran, James Wharram is creating his ‘dream boat’: Mana 24. Here, James’s co-designer Hanneke Boon tells us all about this commemorative self-build kit.
Cornwall’s James Wharram is a bona fide celebrity in the catamaran community. In 1955 he claimed a place in history for sailing himself, two friends, a dog and 200 books to Trinidad in his self-built multi-hull, Tangaroa.
It was a pioneering voyage; James proved the ancient Polynesians were indeed able to travel the oceans via catamaran. Yet in the 1950s this wasn’t even a recognised form of sea travel. “James called the Tangaroa a ‘double canoe’,” says Hanneke Boon, James’s co-designer of many years. “At that time the word ‘catamaran’ wasn’t really known!”
Today his company, James Wharram Designs, is well-established as a leading designer of catamaran kits for the self-build market. To celebrate a full 60 years since James’s maiden voyage, they’re launching a new design – Mana 24. “It’s James’s dream boat!” laughs Hanneke. “At 23 feet six, it’s exactly the same size as the Tangaroa but a lot more sophisticated.”
Epoxy: transforming wooden boat-building
Interestingly, the main reason why James and Hanneke design and build kit boats at all is the advent of epoxy resin. The pair were introduced to epoxy’s potential when they saw Meade Gougeon describe using epoxy to coat, bond and seal wood at the first World Multihull Symposium in Toronto in 1976.
“Meade Gougeon presented a very well-researched paper about epoxy. James was impressed. He said ‘I’ll make boats like origami using this material!’”
However, it wasn’t until they met him again in 1979 at a HISWA symposium in Amsterdam that they were truly convinced that epoxy was the ideal boatbuilding material to make kit-building possible. “Meade Gougeon presented a very well-researched paper about epoxy. James was impressed. He said “I’ll make boats like origami using this material!”
Hanneke has no doubt that epoxy has completely transformed wooden boatbuilding and building in plywood in particular. “Epoxy has introduced a whole new element in fillet-making. It means that not everything has to be cut quite so precisely or so carefully bevelled.”
Mana 24: the boat you can keep at home
Mana 24 will sit in the middle of the James Wharram Designs’ Coastal Trek range. It is specifically designed as a ‘trailer sailer’ – a small, lightweight boat that can easily be stored at home (thus avoiding costly mooring fees) and taken to the water by trailer. It will be offered as a kit of pre-cut plywood parts and accompanying epoxy materials, making the building process much quicker than building from Plans. “James loves to think that within just a few months, anyone with simple tools and a practical bent can have their own boat in which to start having adventures,” says Hanneke.
![wharram catamaran trailer Building the ultimate 'trailer sailer' with epoxy](https://epoxycraft.com/wp-content/uploads/2015/11/Photo-2-1024x768.jpg)
Mana’s design is a deliberate hybrid of James’s and Hanneke’s many ideas and successes over the years. Reviving previously shelved plans for a 23 footer and drawing on elements from the company’s Tiki and Amatasi designs, Mana has a Wharram Wingsail Catrig and a more chined hull. “We’ve always wanted a boat with a more chined hull. Combined with a low-aspect keel it gives good lateral resistance and allows us to reverse the cabin space, giving a wider bunk aft,” says Hanneke. “When we started designing Mana 24, this just clicked.”
In fact, the whole boat has been carefully designed to maximise available space. Although she has just two single bunks in the hulls, the forward-placing of Mana’s main mast enables a dome tent to be set up on the deck – meaning the boat could easily accommodate a small family.
Stitch and glue
The hulls of Mana, just like all of the company’s other designs, will be a series of plywood panels which are ‘stitched and glued’ together using woven glass tape and WEST SYSTEM® epoxy fillets. She also has a ply keel, which Hanneke believes makes for a robust structure. “It forms the backbone of the boat, making it very strong when you beach it or when it’s on the trailer.”
“I’ve always used WEST SYSTEM epoxy; we build professionally with it and I’ve seen it proven time and time again in durability.”
The Mana kit will also include delivery of WEST SYSTEM epoxy, which Hanneke says should make it even easier to build. “I’ve always used WEST SYSTEM epoxy; we build professionally with it and I’ve seen it proven time and time again in durability.”
![wharram catamaran trailer Building the ultimate 'trailer sailer' with epoxy](https://epoxycraft.com/wp-content/uploads/2015/11/Photo-8-1024x768.jpg)
Passing mana to Mana 24
The Mana 24 kit should be available to buy in Spring 2016. At the moment, however, Hanneke is working with a team of volunteers to build a prototype. This will form the basis of the kit, so it’s very important that they carry out the build like a home boat-builder would.
“For example, it took us 37 hours to first coat and sand the inner faces of one hull with epoxy. So, for the kit, we’ve decided to pre-coat the inner hull panels and bulkheads,” explains Hanneke. “It’s easy for us to coat the ply professionally, giving a perfectly smooth finish and this alone should save home builders 70 hours on the total build.”
![wharram catamaran trailer Building the ultimate 'trailer sailer' with epoxy](https://epoxycraft.com/wp-content/uploads/2015/11/Photo-9-1024x644.jpg)
It’s fitting that James, Hanneke and their team are investing so much time and energy into this design. “To the Polynesians, mana is energy and spirit,” says Hanneke. “A tool can gain mana by being used by a craftsman. James and I and all of the volunteers working on this boat… we are all putting mana into her. We are passing our knowledge and experience into her design and our home-builders will pass on their mana when they bring her design to life.”

James Wharram Designs has a new boat on the drawing board, a 24’ trailerable catamaran that slots nicely between the venerable Tiki 21 and 26. The Mana 24 features some new wrinkles in the Wharram design evolution spiral, most noticeably a chined hull. The new design also features a cat ketch rig, which is well known on trailerable monohulls, and it is interesting to see it employed on a cat. No jibs means no head stay tension, giving light mast compression loads, allowing lighter beams. The spiral at work!
The most economical way to enjoy sailing is to build your own small lightweight boat, to keep it at home and trail it to the waters you want to sail in. This gives opportunity to explore many more sailing areas than if based on a permanent mooring and at much lower cost. Whilst exploring this idea I am looking sideways into the world of camping and the living equipment you need for a camping holiday bought at a reasonable price, as against highly priced yachting equipment. All these ideas have come together, resulting in the new MANA 24 design, a catamaran specifically designed for trailer sailing. ~James Wharram

having a look at my melanesia plans (same hull shape as tahiti wayfarer) these hulls seem to be more or less identical with the tiki skeg and rudders added.
An attractive design, for sure, but being trailable in its disassembled state does not make it a trailer-sailer. I can’t wait for the unedited ‘how-to’ launching video to come out. It should be a hoot to watch!

James Wharram: life and legacy of the iconic designer

Julien Girardot meets Hanneke Boon in Cornwall to discover the legend and legacy of pioneering catamaran designer James Wharram
![wharram catamaran trailer](https://keyassets.timeincuk.net/inspirewp/live/wp-content/uploads/sites/21/2023/12/YAW292.FEAT_james_wharram.poster_okay-630x354.jpg)
Falmouth, Cornwall, 1955: a legend is born along Customs House Quay. A smartly dressed young man with wild, curly hair has launched a 23ft catamaran, built in just a few months for the modest sum of £200 (the equivalent of around £6,500 today).
Rigged as a ketch with battened junk sails, the aptly named Tangaroa (meaning ‘God of the Sea’ in Polynesian) marked the beginning of the epic Wharram story.
At the time, catamarans were considered dangerous and eccentric, while yachting was a pastime largely reserved for high society. But sailing already has other visionaries. On the deck of Tangaroa, beside James, are two young women: Jutta Schulze-Rhonhof and Ruth Merseburger. In puritanical post-war England, setting off to cross the Atlantic with two young women – and German ones at that – was downright shocking! But these three young people care not a jot about conventional thinking. They dream of adventure and their enterprise is an act of defiance.
For years James Wharram has nurtured a passion for the history of sailing pioneers and the ethnic origins of the multihull. Devouring every book on the subject he could lay his hands on, he discovered the story of Joshua Slocum, the first solo circumnavigator (1895-1898), and the voyage of Kaimiloa by the Frenchman Eric de Bisschop. The tale, published in English in 1940, of de Bisschop’s attempt to prove the seaworthiness of double canoes by making a voyage from Hawaii to France on a catamaran he had built on the beach, became Wharram’s primary source of inspiration.
![wharram catamaran trailer](https://keyassets.timeincuk.net/inspirewp/live/wp-content/uploads/sites/21/2023/12/YAW292.FEAT_james_wharram.tangaroa_jim_biscay_1955-630x355.jpg)

Wharram disagreed with many assumptions of the time, and his first Atlantic crossing was an opportunity to refute Thor Heyerdahl’s theory on the settlement of the Pacific islands. Wharram contested the assertion of the Danish anthropologist who, after his voyage aboard the Kon-Tiki in 1947, affirmed that the boats used were simple rafts. Wharram was convinced that the boats were more akin to double canoes with sails, capable of going upwind and holding a course. These early multihulls, consisting of two hollowed-out tree trunks, were connected by crossbeams bound together with plant fibre. The sails were probably made from what is known as ‘tapa’ in Polynesia, hammered tree bark, which was also used to make clothes.
The three young adventurers left Falmouth on 27 September 1955 on a boat loaded with books, basic foods, and very little else. Despite a fraught passage, encountering storms in the Bay of Biscay and being suspected of being spies by Franco’s Guardia Civil, the trio successfully crossed the Atlantic and reached the island of Trinidad on 2 February 1957.
Without a penny to their name, they adopted a simple island life, and Jutta gave birth to her and James’ first child, Hannes. The unconventional polyamorous family lived aboard a raft inspired by the floating dwellings of the Pacific, nicknamed ‘the paradise island of the South Seas’. Tangaroa, now tired, was abandoned, as Wharram decided to build a new catamaran. By chance, two solo sailors came to anchor in the bay where the Wharram tribe lived afloat, and the legendary Bernard Moitessier and Henry Wakelam helped Wharram build his new design, Rongo.
![wharram catamaran trailer](https://keyassets.timeincuk.net/inspirewp/live/wp-content/uploads/sites/21/2023/12/YAW292.FEAT_james_wharram.tangaroa_in_falmouth_1955_3-630x354.jpg)

Thanks to the experience of his first transatlantic voyage, as well as knowledge gathered from Wharram’s endless reading, Rongo was much more accomplished. While Tangaroa was flat-bottomed, Rongo has V-hulls. To prove the design’s seaworthy qualities, Wharram decided to tackle the North Atlantic, sailing from west to east with his two companions. This route was known to strike fear into the hearts of multihull sailors of the time, as the two previous attempts had tragically ended in two deaths.
The crew left La Martinique for New York on 16 April 1959, one year after Rongo’s construction began. The return voyage to Conwy in Wales took 50 days, but the gamble paid off, and Wharram’s new design was the first to achieve what many thought impossible. The curly-haired eccentric became something of a celebrity, and following his great Atlantic adventure, James published his first book, Two girls, Two Catamarans. The years that followed were Wharram’s golden age, with plans released to suit every budget and every dream. Soon there were Wharram designs all over the world, connected by a powerful community spirit.
Drawing a Wharram
My own journey to this remote corner of Cornwall began decades before. After 15 years of travelling the world, inventing and reinventing my life, including many years living in the Pacific islands, I felt the need to capture these experiences by creating the boat of my dreams.
![wharram catamaran trailer](https://keyassets.timeincuk.net/inspirewp/live/wp-content/uploads/sites/21/2023/12/YAW292.FEAT_james_wharram.illustration_sans_titre_1-630x354.jpg)

While living in Tuamotu, I was involved in several incredible projects to build traditional sailing canoes under the directive of talented local Tahitian boatbuilder, Alexandre Genton (now chief of operations at Blue Composite shipyard in Tahiti). At first we launched small single-seat sailing canoes with two outrigger floats. These are the simplest way to sail: a sheet in one hand, a paddle in the other, which you plunge over the side of the canoe into the water, and it makes a perfect rudder. Then we built a larger version, Va’a Motu, for a hotel in Bora Bora, of splendid stripped kauri planking. Finally, we worked with the local population to build an ambitious 30ft Va’a Motu with a single ama, on the atoll of Fakarava in the Tuamotu archipelago.
Curiously, after many experimental trials at building and sailing canoes, my imagined ideal yacht turned out to be something very close to a Wharram design, which I learned as soon as I shared my first cautious sketches with friends. I realised I had to meet James Wharram.
In October 2021, I dialled the number of JW Designs. A woman answered; James’ long-term life and business partner Hanneke Boon. I tell her my ideas to build from one of their plans: the Islander 39. We began an email exchange and when I asked her what James thought of this model, in November 2021, less than a month before he died, she replied: “James is enthusiastic about your project. He’s now 93 years old and nearing the end of his life.
![wharram catamaran trailer](https://keyassets.timeincuk.net/inspirewp/live/wp-content/uploads/sites/21/2023/12/YAW292.FEAT_james_wharram.illustration_sans_titre-630x354.jpg)

“He has been looking at the Islander 39 design for several years and often says, ‘I wish I had one myself.’ It’s the only Wharram design that has never been built, so your project is a wish come true for him.”
On 14 December 2021, James Wharram passed away. Out of respect for the bereavement, and due to Covid-related travel restrictions, we decided to postpone our meeting. Some months later on a beautiful spring afternoon, I landed in Plymouth with my friend and artist Benjamin Flao, himself the owner of a Wharram-designed Tiki 28, and headed for Devoran near Truro in Cornwall, the stronghold of the Wharram family.
Hanneke welcomes us into her office. It is a beautiful wooden cabin, warm and bright, overlooking the changing lights of Cornwall. The place looks like a museum telling the story of a life of travel and passion through yacht models, photographs and unusual objects. James is there, you can feel it. A glance at the shelves of the library shows an impressive array of rare and precious books, mostly dealing with navigation and shipbuilding in Oceania, and demonstrates the seriousness with which Wharram and Boon studied the history and technicality of ‘double canoes’.
“I’d like our boats to be called double canoes and not catamarans, which I think is a mistake,” Hanneke explains. The word catamaran, originally pronounced ‘catamaron’, comes from the Tamil dialect of katta ‘to bind’ and maram ‘wood’, as they were actually one-man rafts used to work on the outer hull of ships. The English pirate and adventurer William Dampier, in the 1690s, was the first to describe a two-hulled vessel as a catamaran, but although catamarans might be the commonly accepted word nowadays, it’s actually a mistake.

Hanneke unfolds the Islander 39 plan on her drawing board. Like all Wharram plans for half a century, it has been marked with her signature. Despite this unique pencil stroke, she has remained in the shadow of Wharram’s mythology for 50 years. Since 1970, Boon has drawn the majority of the construction plans by hand. They’re works of art and the best way to imagine yourself aboard a Wharram. Without her, JW Designs would not be what it is.
Originally from the Netherlands, Boon grew up in a family of sailing enthusiasts. By the age of 14 she was already building small canoes and at the age of 20 she joined the Wharram team and quickly became his co-designer. They criss-crossed the Atlantic twice in quick succession aboard Tehini, the crab claw-rigged double canoe on which James and several women lived for 10 years. Since then, Hanneke has escaped from her office whenever she can to sail thousands of miles on all the seas of the world, always using a double canoe.
Those radical vessels included the Spirit of Gaia, also built on site, through a sliding door next to Hanneke’s office. It was aboard this 63ft Pahi, Wharram’s flagship, that the Wharrams sailed around the world from 1994 to 1998. James described Spirit of Gaia as “a beautifully shaped woman he was in love with”.

In Wharram’s wake
James and Hanneke’s home is a former veterinary surgery. The furnishings are basic, with only the essentials, but the doors close by themselves, thanks to an ingenious system of weights, ropes and pulleys. Benjamin and I offer to shop and cook, and in the living room, we put the dishes down and eat on the floor, like on the deck of a Wharram.
Jamie, James and Hanneke’s son, joins us for the meal with his partner Liz. “James has remained the icon of the business, but it’s really Hanneke who has been doing the job for the last 10 years. She is JW Designs,” confides Liz.
Jamie is at first more subdued, but talking to him you soon discover a true character. Given the world he grew up in, it’s surprising to learn that sailing is not really his thing: “I get bored quickly at sea and I’m sick most of the time! I prefer to be underwater. Above the line is not my thing.
![wharram catamaran trailer](https://keyassets.timeincuk.net/inspirewp/live/wp-content/uploads/sites/21/2023/12/YAW292.FEAT_james_wharram.img_0307-630x355.jpg)

“I do like the calmness of the ocean though, that parenthesis effect, detached from our hectic lives on land. In fact, I think the best thing about sailing is remembering long voyages, not making them,” Jamie jokes.
But he is keen to preserve Wharram’s legacy and the couple are thinking ahead to when Hanneke can no longer hold the fort. “As long as Hanneke is alive, the business will be run in her own way. But it’s certain that something will be put in place to enable people to continue to acquire the building plans, at the very least, this service will remain guaranteed.”
Back in the office next door, Nicki John answers clients and sends plans around the world. She’s only been with JWD for a couple of years, but that’s long enough for her to fall in love with the company’s story.
“One of the things I loved about James was that he came in every day. He’d knock on the door and jokingly ask, ‘Do you have time for some gossip?’ And then he’d tell me all sorts of stories. His travels, the women he had shared his life with, it was fascinating. When he was 18, he hitchhiked to Europe, smuggling coffee on the black market to finance his adventures. James’ story is just phenomenal.
![wharram catamaran trailer](https://keyassets.timeincuk.net/inspirewp/live/wp-content/uploads/sites/21/2023/12/YAW292.FEAT_james_wharram._dsc4019-630x354.jpg)

“One day James came in, took out a plan, unfolded it as he sat down, and said, ‘Aren’t they beautiful?’ James was deeply convinced of Hanneke’s talent. He never stopped admiring her,” Nicki says fondly.
The community Wharram fosters is unique. Nicki shows us a photo that defines the ‘Wharram spirit’, of the hull of a Wharram being lifted out of the second floor window of a home in England. With no shed to build their Wharram design, they decided to use their living room as a boatyard. “This picture shows that if you really want to build a Wharram, you can do it anywhere,” says Nicki, “During Covid, we sold a lot more plans. Confined, people dreamed of freedom and took time to figure out how they wanted to live their lives.”
Now it’s Hanneke’s turn to shine as the head of JWD. In contrast to the technologically-led path that sailing often follows, James and Hanneke’s ‘low tech’ approach drives those who follow it to reconnect with past knowledge, practices, and philosophical approaches to our relationship with the world and the way we live in it.
Their love of minimalism is also at odds with many trends in modern yachting, but it brings its own luxury. The joy of not having too much of anything allows you to make room for the essentials, and for the beauty that surrounds you.
My dream of building Wharram’s unfulfilled plan, the Islander 39, remains. I’m in no hurry. Like the libertarian vision of James Wharram, it endures.

Tiki 36, Wharram design catamaran
- Add to quote
Has anyone seen this new build design by BOATSMITH out of Florida? If any vessel can push me over to a Catamaran, this is it. Traveling out to Nigeria in a few hours, but will pick up internet access once there, I'd appreciate your views now though. I love the concept of this vessel. 32' waterline --- 28" draft --- 4500 lbs displacement --- 650 sq. ft sail area = Hello! comments please. These numbers add up, why are there not more of them out there?
![wharram catamaran trailer](https://www.sailnet.com/d1/avatars/s/0/276.jpg?1669676471)
Why are there not more of them out there? Because Wharrams are usually a pain in the butt to sail, most are very crudely built (I understand that Boatsmith does a nice job) , and do not sail worth a darn? Why else?

Why else indeed? It's all about the sailing for me. Never been on a cat of this size but I did like the numbers on paper - don't you?
okay, i'll bite Jeff. Could you actually explain the deficiencies of the sailing characteristics vs other comparable ocean going cats. Any boat, home or professional built can be crude. So please spell it out for those of us that are interested in learning about different platforms. Otherwise, as with my personal vehicle my motto is: Absolutely Nothing Beats A Hummer .
Jesus H.....TDW, I wish someone would have told me! The Kombis went 5 months ago to my daughter's boyfriend, my hair went in 1999 (after the Brazil 1200' dive), my denims went last year because I'm too fat, but the tie dye shirts, sandals, head-bands and weed stay with me! Now, listen-up you lot! I see a vessel with some interesting numbers. This Wharram is built by a professional. Not the back yard project you're thinking about. Look at the displacement vs the waterline length vs sail area... this thing could move and I want to know why not- in your opinion- anyone out there - who isn't stoned...
Nemier, Do you have a link to the Tiki 36 ? I can't find the site.
![wharram catamaran trailer](https://www.sailnet.com/d1/avatars/s/139/139037.jpg?1592288369)
Thomas Forth Jones had some good things to say about Wharram's designs. And he should know he built a couple of them as well as sailed them for years. In my opinion, and I'll start by saying that I've always like Wharrem's designs but it's best strengths is it's biggest weaknesses. It's biggest strengths are that the designs are both simple to build and sail while still getting high marks for stability and strength offshore. Unfortunantly even when built by professional builders they still look homemade-ish. They're also not the most accomadating boats in the comfortable interiors. Add in that the vast majority of sailors are never going offshore and they don't have a good resale. Most people want more space so opt for a catamaran that has a built up bridge deck. So unless your really planning to keep the boat on an anchorage most of the time when your not sailing to exotic locales then your going to pay a high price to keep a boat on a slip that's not overly comfortable for weekend cruising or parties.

Here's the Boatsmith link Wharram Catamarans And here's Wharram's site James Wharram Designs -Home of the self-build Catamaran.
I went onboard the Boatsmith Tiki 30.... at the Miami Boat Show two years ago. Absolutely gorgeous piece of work. I have no connection with the builder but if I could afford him and his crew they would be working on my boat. As for the Wharram designs, I have no direct experience sailing them so I will leave comment on that to others.

Sometimes the arrogance of some of this forum's members really makes my day happier and puts a smile on my face. :laugher Sure, Wharram cats, Piver tris and the likes of it are nothing but rubish. I wonder why so many crossed so many oceans so many times. Often faster and safer than their professionally built counterparts... But I do understand the owners of plastic-fantastic latest generation multi thousand $ boats, after all sailing, let alone cruising, shouldn't be allowed to the masses and those who are anything short of milionairs should be all sailing nothing bigger than toppers and laser dinghies...

TDW and why are you not at the boat show?????
Simon, Had to move the Womboat to her new home today. Going to try and avoid the weekend crowds, heading off to the show on Monday. You're not in town are you ? Cheers Andrew
Jeff, I'm kind of new around here and don't know much about you and your vast sailing experience on all types of sailboats. Did you base your opinion on how Wharrams sail on personal experience sailing a Wharram, or by rumor? How did you come to the conclusion that they don't sail? I personally sailed Boatsmith's Tiki 30 from Miami to Jupiter last year, and we were constantly surfing up to 17 knots. Then we beat up the channel and it pointed ok, with a ballanced helm. After a Worrell 1000, sailing my cruising cat thousands of miles, a Tornado Olympic trials and several other world championships, I base my opinion on catamaran experience. How bout you?

Expensive compared to what???
Hi Boatsmith, are you showing the 36 at the Annapolis show next month? I would like to see it! Cheers Nick

Back in the late 60s as a teenager with ambitions(never realised) to sail the Alantic it was the 28 foot Wharram Tane that appealed both to my "flower power" sentiments ; my pocket and its design and construction concept Never owned one but occasionally see them about and get tempted. Would love one of the small day sailer ones particularly when getting my 33 foot ketch out for a day sail!. Certainly time spent last year in NZ where I saw several in their true environment of the south Pacific rekindled the facination of my youth! Wharram himself always argued that there was a philosophy involved in his cats-either you like them or loath them.
Hi Boatsmith, Expensive compared to the Wharrams on sale. At the time I was looking at a recent vintage Pahi 32 for $60k.
![wharram catamaran trailer](https://www.sailnet.com/d1/avatars/s/121/121440.jpg?1592288368)
I'd point out that many of the earlier Wharrams were home-built and as such often had flaws due to the deficiencies in their construction rather than their design. I've sailed on a few of the Wharrams and agree that they're not as weatherly as some other designs, and Wharram's designs tend to be less rigid than other catamaran designs, and as such can have problems related to the lack of rigidity. I do not have any experience with the Boatsmith built Tiki 36s. But, I would point out that the open bridgedeck design tends to leave anyone helming the boat for any period of time in bad weather, relatively exposed and uncomfortable.
Many early Wharrams are very flexible vessels. This is in part due to design and also to lack of building and rigging finesse and lack of maintenance. Wharram's newer designs are lashed together. This technique applied with diligence and modern ropes will yield a much more rigid structure. Part of Wharram's design philosophy is that a minute amount of flexibility in the beam to hull connection serves to absorb the intense shock loading inherent at these connections. Indeed if you look at a boat with aluminum cross tubes it is very common to see stress cracks and repairs. The open bridge deck boat certainly does leave a helmsman exposed, which over time in inclement weather can be both uncomfortable and dangerous. Much like many small monohulls. On the Tiki 36 we addressed this issue by adding a windscreen and roll down curtain/windows for the helm station.
Say what you will about Wharram catamarans, but show me another multihull design with the proven seaworthiness of his Tiki range. Nothing comes close to the number of ocean passages successfully completed in these simple boats. Even the Tiki 21, which James Wharram never intended as an offshore voyager, has circumnavigated. And the same boat, again sailed by Rory McDougall, just completed a double trans-Atlantic this summer, the first leg over as part of the Jester Challenge, and return to England just for the hell of it and to take the boat back home. Needless to say, the larger Tikis are simply as seaworthy or more so than the Tiki 21. Many Tiki 26's have crossed the Atlantic, as have Tiki 30's and of course the larger Tiki 38, Tiki 46 and so on. These passages were not stunts, nor were they completed because of "luck." People who build and sail these designs tend to be out there living the voyaging life and going wherever they please, rather than debating the merits of boat design on Internet forums. I have sailed the Boatsmith Tiki 30, including a delivery trip to Nassau last summer. David has raised the bar on these designs without a doubt, showing what's possible when a great design is built to exacting standards by professionals using state orf the art materials and technologies. Sure there are some ratty home-built Wharrams out there. Many people who build these boats have no idea what they're getting into and lack the skill and the funds to build them to a high standard. Yet, the designs are so forgiving they still manage to build them and often sail them far. As for the overall appeal of the designs, as Wharram himself said, you either love them or hate them. I happen to love them because I know what they can do and I think they look really cool anchored in a tropical lagoon or pulled up on the beach somewhere.
We had our first family cruise this summer on our Contour 34 - and while it was great - the appeal of something like the rigid deck of the wharram would have been even better. I've not sailed one - and am a bit concerned about the possibility of pitching given the pinched ends, so I lean a bit more towards Richard Woods' designs. Assuming the next couple of years are as successful as this years cruise, I'd expect that we'd be looking for something like this boat in 2-3 years time. I think a boat like this one would be ideal.
C'mon down and go for a sail grmitche

MANA's 23'6" hull length has a special significance for James Wharram. In 1956 he made the first successful catamaran voyage across the Atlantic in his first catamaran, the 'Tangaroa', also 23'6" long. In trailer/sailer design every increase in length equals harder launching and recovery work. At 23'6"- 7.15m hull length MANA 24 sits between ...
All these ideas have come together, resulting in the new MANA 24 design, a catamaran specifically designed for trailer sailing. In trailer/sailer design every increase in length equals harder launching and recovery work. At 23'6"- 7.15m hull length MANA 24 sits between our TIKI 21 and TIKI 26 designs (both very popular trailer sailers ...
The Wharram Tiki design was a natural choice for Dave because the designer has always approached his work from a builder/sailor perspective, rather than as an independent exercise in naval architecture. Simplicity and practicality rule, and in many ways these boats are the extreme opposite of whats displayed at boat shows across the country.
Mana 24 will sit in the middle of the James Wharram Designs' Coastal Trek range. It is specifically designed as a 'trailer sailer' - a small, lightweight boat that can easily be stored at home (thus avoiding costly mooring fees) and taken to the water by trailer. It will be offered as a kit of pre-cut plywood parts and accompanying ...
While ocean-voyaging catamarans have been the main focus of Wharram's design work, his plans catalog includes a few smaller boats suitable beach cruising. The Tiki 21 that was recently profiled here in Small Boats Monthly crosses the line between the two pursuits but is still a bigger boat than many people want to build or trailer. The Hitia 17 and the Hitia 14 are based on the same hull ...
Posts: 41. Review of a Wharram Catamaran. Dear Forum: I have looked at a Wharram Catamaran, namely the tiki 38, that I have thought about building and then living on it in retirement. This way I can do what really brings me inner peace, sailing, and live on the boat too. I have looked at the wharram site and their builders as well.
The quality of the Wharram self-build catamarans is reflected in their popularity, excellence of craftmanship and sound sailing qualities. More than 50 years on - with over 10,000 sets of plans sold and thousands turned into proud vessels - Wharram 'Cats' can be seen in harbours across the world, maintaining the highest reputation for surviving ...

James Wharram Designs has a new boat on the drawing board, a 24' trailerable catamaran that slots nicely between the venerable Tiki 21 and 26. The Mana 24 features some new wrinkles in the Wharram design evolution spiral, most noticeably a chined hull. The new design also features a cat ketch rig, which is well known on trailerable monohulls ...
Choosing a 21' to 27' Wharram Catamaran Design. James Wharram Designs has been very productive since the first transAtlantic voyage by a Wharram double canoe in the 1950's. Unfortunately this has resulted in a glut of beautiful designs in the 21 to 27 feet range. These include: the Coastal Trekkers Tiki 21 and 26, the Classic Hinemoa and Take ...

This was the first west-to-east crossing of the Atlantic by catamaran or multihull. The story was told by Wharram in the 1969 book Two Girls Two Catamarans. [7] From 1973 Wharram was assisted by his co-designer Hanneke Boon. [8] In 1987-92 James and his partners built a new flagship, the 63-foot catamaran Spirit of Gaia, which they sailed into ...

The Tiki 30 is one of Wharram's best sailing designs. He does refer to it as a backpacking boat. It also is a 30' sailboat that has a cockpit that seats 10 easily. It also is a very comfortable seagoing boat that will fit onto a trailer or into a container and be transported anywhere in the world cheaply.

The catamaran designs that British multihull pioneer James Wharram first created for amateur boatbuilders in the mid-1960s were influenced by the boats he built and voyaged upon during the 1950s. These "Classic" designs, as Wharram termed them, feature slab-sided, double-ended, V-bottomed plywood hulls with very flat sheerlines and simple triangular sections.

Lit Bits. Dec. 18/2020: James Wharram, who first came to notice back in the 1950s after sailing a crude homemade catamaran across the Atlantic from England to Trinidad with two occasionally (and famously) unclad women, has cut a unique trail through the firmament of modern yacht design. He has always planted his flag far outside the boundaries ...

Hi! I own a Wharram Pahi 42. We bought her about 10 years ago now from the original owner/builder. I'd always dreamed of building a wharram, but as other posters have said, you can buy a used one usually much cheaper, and you get on the water immediately. But unless you get a really good one, you will likely spend a LOT of time fixing her up, and a lot of money upgrading sails and equipment ...
James Wharram was the pioneer of offshore multihulls, making his first Atlantic crossing by catamaran in 1956 and the first ever North Atlantic West-to-East crossing by multihull in 1959. He started designing for self-builders in 1965. In 1973 Hanneke Boon joined him and became his co-designer.
A Global Family Of Sailors The Wharram World circles the globe. Wharram catamarans have been built and are sailing in all the World's oceans and can be found in far away ports and anchorages. With over 10,000 sets of Plans sold since the 1960s this is not surprising. Many of the builders and sailors of Wharram catamarans are now writing blogs about their exploits and
