James Wharram: life and legacy of the iconic designer

Yachting World

Julien Girardot meets Hanneke Boon in Cornwall to discover the legend and legacy of pioneering catamaran designer James Wharram

pahi 63 catamaran

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 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.

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.

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.

“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.

“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.

“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.

The words sustainable, low-impact, eco, and community involvement have become buzz-phrases in the tourism industry. They conjure up images of sophisticated, adventure-minded travelers jetting off to far flung corners of the world to kayak or surf or trek—but we believe that sustainable, community-oriented, ethical business begins at home. Our home is Montauk, New York.

The Montauk Catamaran Company’s sailing catamarans are the James Wharram designed Pahi 63 S/V Mon Tiki Largo , the Tiki 38 S/V Mon Tiki  and the Tiki 26 Mon Tiki Mini . All three of our boats were built right here on Long Island from the keel up, by local craftsmen, using low-impact construction methods.

Because safety is our first concern, our boats were constructed in accordance with the Code of Federal Regulations (CFRs) under US Coast Guard supervision, and to their exacting Inspected Passenger Vessel standards. Every phase of construction, from initial design, to hull construction, to rigging and deck layout have undergone rigorous US Coast Guard review and certification. Only USCG Inspected Passenger Vessels are permitted by law to carry more than six passengers, and the S/V Mon Tiki Largo and  S/V  Mon Tiki  are the only sailing vessels in Montauk that meet this exacting standard for design and safety.

Our boats are also low-emissions vessels. Primary propulsion is provided by a powerful sail plan, and sail we do! Auxiliary propulsion is provided by ultra-clean, ultra-quiet Honda engines, but under normal operation these engines are used for harbor maneuvers only. Once at sea, our boats are true sailing vessels. During your time aboard, the sounds you’ll hear are the sounds of wind and water.

Complete, clear and detailed plans to build your own Wharram Catamaran, that have often been described as a 'course in boat building'. All Wharram building plans are drawn for the first time builder, so anyone with a modicum of practical ability can build one of our designs. Wharram designs are all based on decades of actual building and sailing experience of the boats, so you can be confident in its sailing capabilities and safety.

The PAHI Designs are a different visual/sculptural approach to the basic design elements inherent in the Classic Designs. From the coastal trekking Pahi 26 to the impressive 63' flagship of the Wharram fleet 'Spirit of Gaia' - the PAHI shape is more evocatively 'Female'. Constructionally, they are simpler to build, using epoxy fillets instead of wood joints, and are designed to use softwood plys which are coated and glassed with epoxy to achieve a durable finish. The PAHI designs were the first to use rope lashings to attach the crossbeams, giving a shock absorbing effect, without the need for metal fittings.

cruising catamaran average speeds

Discussion in ' Multihulls ' started by Bruce Woods , Nov 27, 2007 .

Bruce Woods Senior Member

Recently I was asked by a friend, contemplating the purchase of a cruising cat, what average speed did I use for calculating passage times. The answer of 5 to 6 Knots Was not what they wanted to hear for a 10.5 meter bridge deck cat. I know my boat is not slow, as I come from a racing background and race the boat regularly. With all the "optomistic" speeds reported in sailing magazines I can understand why novices think a cruising cat should be able to average maybe twice this. Sure, when conditions have been perfect we've completed 100 nm in daylight hours, but your never going to maintain this for a cruising season. As an execise, I've averaged the 2007 308 nm brisbane/gladstone multihull race results, excluding the fastest and slowest boat. For a predominantly downwind race in fresh conditions (fresh enough for two large cats to capsize) the average speed for the 14 finishers was approx 10 knots, for an average boat length of approximately 12 meters. So if "joe crusiser ",with the wife , kiddies, and all their cruising crap, plus a strong desire to get to the destination in one piece can average half this for a complete cruising season ,their probably doing well. What passage averages do the experience multihull cruisers out there work on when planning a voyage 6 months hence. Regards

Short fat cats slow. Long slim cats fast. Look at Gunboats 62 and 48. http://www.northsails.dk/uk/tribe.asp http://gunboat.info/ http://www.deltayachtsbrokerage.com/news/YWorld_gb62.pdf Pericles  


waikikin Senior Member

Bruce, I've mostly done coastal cruising in cats(had a beach marine 10m) & raced monos, & mostly if boatspeed drops below about5.5 knots, I turn on the engine & "make it happen" & comfortable speed of 7.5-8.5 is much more satisfying. Because my wife is scared of the dark, I often did daylight hops of up to 70 miles , leaving early(often not much breeze) & planned to enter port before 3 PM(east coast looking at sun/glare to enter sucks!). Of coarse every one likes to talk about the 14knot average runs but often theres a bit of zigging & zagging in the way as well as the 22knots that I saw on the log for at least 300-400 metres. Regards from Jeff.

Good Morning... IMHO...if a weight cautious cruiser with perfect wind and sea conditions gets better than 1.5*(lwl^.5) then he is doing good. He may not get too much sleep but he will definitely be jetting. This excludes surfing and it is for a multi. A mono will never break the 1.34 rule unless it is a specialized hull designed to plane or while surfing with optimal wind and sea conditions. I don't care how slim or trim it is advertised. It is designed to displace period. I have never seen better than 1.2 on a monohull cruiser and that was with a beam reach in 50 mph winds. That's my opinion and it is subject to the freak moments when the rule and my observation can be broken but those times are not consistent or often. J  


catsketcher Senior Member

Slow is the way to go Hello Bruce, Your speeds are a little less than what I plan on. I usually think about 7-7.5 knots on the chart. (East Coast Australia - usually sailing downwind) We have done less and more over the day (usually daylight coastal hops) Our best run ever was 160 miles from Coffs to Southport in 16 hours. (hand steering all the way) The problem with letting it all hang loose is it is harder work. It doesn't take long before you realise that getting there happy and easily is better than getting there earlier and frazzled. I cruised a Twiggy tri for a few years and we used to fang everywhere at first - but we got tired and bummed out. I am a racer too but even my thirst for performance gave way to desire for peace and comfort. Before people get excited about speeds on test sails they have to remember that most cruising boats are sailed under autopilot by shorthanded crews. What they can achieve in ideal conditions on a short sail with lots of people on board is vastly different from what cruisers sail at. Kankama (a 38ft strip plank Chamberlin) got passed by about 3 cruising boats in 3 seasons cruising. That was when we had no kite up so there aren't that many fast boats whizzing around. A fast looking long cat with a big rig will probably go around with smaller sails and fewer extras than a smaller boat. The contrary thing about talking too much about extra performance is that it costs so much. A carbon 60ft cat will go twice as fast as a simple 35footer. It will cost maybe ten to thirty times as much so you have to stay at work for a much longer time to get one (if you get one at all) The fastest cat is a simple one that gets you out there a season or two earlier or out there at all. cheers Phil Thompson  
cruising speeds Thanks catsketcher for your knowledgeable and valued input. With no motor we recently averaged approximately 7 knots for the 1400 odd nm non stop, single handed Carnarvon /Darwin run but only 3.5knots for the very light weather mostly windward return. The speed data published in recent times justifying one particular design over another needs to be placed in context, especially for those ineperienced folk buying a cruising multihull for the first time. Regards  


charmc Senior Member

It's important to remember that nearly all reports of long high speed passages are decribing racing or record attempts. Most well designed multihulls can sustain 15 -20 knots under the right wind conditions ... but most cruising crews can't. Phil, you nailed it. Sailing fast is hard work. Exhilarating and loads of fun for a while, but certainly not a part of cruise planning.

We averaged 8 1/2 knots between Brisbane & Airlie beach, in a 38 foot Oram Mango. Anchored every night, and got there in 5 days.

I would agree with the other comments. It is indeed hard to sail over 200 miles a day. In part because the further you sail the slower the average speed. But mainly because, when cruising, high speeds are uncomfortable. Having said that, here is a quote from a friend who just sailed a monohull from the Galapogos to Costa Rica. Her only other sailing was on a 33ft catamaran called Rush, a boat I crossed the Atlantic in last year. And also a boat that I found to be just about the most uncomfortable catamaran I had ever sailed. Anyway, she said: "Monohulls versus catamarans! Well is there a choice!! I mean to say, a choice where everything is tied down, even straps to tie me in the galley, coffee cups 2/3rds full so it doesn’t spill, being flung from side to side versus a full cup of coffee, sitting or lying in comfort outside and not being flung out of bed. There is nothing worse than your brains racing from side to side in your head when you are lying down. You know, it could have been worse, there is always worse. I have bumped around in Rush at times too but then the seas were a lot worse than we encountered on this trip. Pity help it if they had been worse, I can now see why so many monos motor sail. At least to get a break from the constant motion" Cruising a multihull fast is possible, but why do it?? You are living on board, not just going for a day sail, so you should make it as comfortable and relaxing as possible. I usually reckon that peak speeds are about twice the average speed. So if you average 8 knots that means you have often done 16 knots and you will swear the log never read below 12. The best I have ever done was 600 miles in 3 days when racing a 35ft Banshee catamaran and 250 miles in 24hours, again when racing. The best days run when cruising was 185 miles in my 32ft Eclipse, a boat I had earlier sailed at over 20 knots when day sailing, and a boat that when racing proved faster than, for example, all the French production cats. You can see more about cruising speeds on my website www.sailingcatamarans.com Good sailing! Richard Woods of Woods Designs

150 miles is a good cruising days run on any boat. The reality is that quite often there is no wind in the middle of the ocean. Unless you carry enough gas/diesel to motor when ever you drop below 5 kts your average will drop significantly.  


oldsailor7 Senior Member

Comfortable short handed fast cruising is possible. In 1981 John Hitch, Holly North and myself sailed to lord Howe Island in Johns Crowther Spindrift 45 catamaran, in a club cruise. We were on auto pilot all the way. We reefed as necessary for comfort rather than safety. We averaged 10.2 kts for the trip and arrived warm and dry, unlike other monohull sailors who arrived cold, wet and miserable.  


souljour2000 Senior Member

This is a good thread...some very interesting appraisals of the the relative values of a boat's speed...Not having spent much sea-time above 5.5 knots ...I hadn't thought about the effects of speed or what ripping along at almost 8 kts would be like in say, a speedy, modern 36-40 footer...in terms of comfort and stamina on a long cruise with long intervals at potentially fast speeds...My own boat has a good motion and a solid feel...but for what it's worth, having read the above posts... I feel better about my old C-40's speed now... She should do 6 knots easily much of the time and her theoretical hull speed 7.06 kts should be just fine...now that the lightbulb has finally flickered on... I think I can squeeze 100 mile day by myself fairly easily from her depending on the route taken...140 with another crewman...and sometimes more....when she's on her rails in higher winds and we want to get some sea-miles behind us. I know this thread is about cats but it's actually very illustrative to some of us mono-coquers...thanks much my bi-cameral friends and carry on... please...

The fastest I have ever made a crossing was on a 550 mile delivery where we averaged about 16kn. While it was an awesome slay ride, the entire time we kept wishing we could slow the boat down. But with just five of us on board, and two down with seasickness we made the decision that it was safer to allow the boat to push, than to try and manhandle the sails (this was on an Andrews 70). Luckily the crew found their sea legs before we hit land, and we were able to safely shorten sail as we entered the shipping channel, but there was some discussion of dropping the jib overboard if we couldn't get her under control by then. Luckily this was an all out racing machine designed for the Trans-PAC, so these speeds, while high, we're well within her design and gear limitations. But it was a lot of work keeping her at that speed. In large part because the auto-pilot couldn't react fast enough, and so she had to be hand steered the entire way.
