Too Much Choice

There are a great number of large cruising catamaran and other multihull plans out there. I think one of the reason is that building a large catamaran is easier than building a cruising size keelboat. Many designers feel confident that the home builder has a good chance of success in putting together quite a competent multihull.

I have not included all the large multihull plans and kits I have found, nor have I included many of the home made single effort catamarans that are out there.

I try to be accurate and check my information, but mistakes happen. ALSO keep in mind that not all boat plans are well designed. Old Banks Dories are particularly tricky because they were notoriously unsteady until they had some weight in them. Check the boat forums, many people have built dories. I have not built these boats and I can't recommend or proscribe any.

The Multi Chine Proa

Concept - Plans - Pics - Rig - Sail - Details - Sail test

Basic Concept

Cutting plans.

The main hull has three parts: lee plank, luff plank up and luff plank down. Every plank could made from mirrored halfs from 4mm plywood. Next step is to glue a stringer (20x20mm) along the upper edge of the lee plank (may be a second one into the middle) and of the upper luff plank for fitting the decks later. Annother stringer should fixed at the below edge of the upper luff plank. For more stablity use a keel batten (20x20 mm) as backbone. Then the traditionary holes through the below edges of the lee plank, keel batten and below luff plank.

Building Pictures

Analogue to the main hull (vaka) build the ama. Here it's more simple because the hull is symmetric and it straighten itself after putting the bulkheads in. Cutting plan for the Ama.

The rig functions like a seesaw. With changing the bow after shunting you pull down the yard with the sail to the new bow.

Fine demonstrated is this rig at the homepage of Gary Dierking or in the Gibbons-Special at multihull.de. This Gibbons/Dierking rig has a simpler handling in opposite to the Crab Claw sail. Also you should do easier maneuvers at the overcowded lakes here (Remark: This I thought before I tried it in reality. See 'sailing experiences' below).

Jzerro: The oceangoing Pacific proa

Helen Fretter

  • Helen Fretter
  • April 8, 2021

Jzerro is a Russell Brown-designed proa, which is being prepared for a 14,000-mile record bid from New York to San Francisco

proa sailboat plans

The great Californian Gold Rush of the 1840s and 1850s saw over a quarter of a million people follow the sun to the west of the United States, each dreaming of making their fortunes.

The ‘49ers’, as the early migrants in the first wave of 1849 were known, mostly travelled by ship, sailing from New York to San Francisco westabout around Cape Horn . It was an arduous and dangerous journey, but over 500 vessels – from majestic clipper ships to hastily converted whaling boats – made the voyage in 1849 alone.

The route is as much a part of the American maritime heritage as the clipper tea routes are a part of Britain’s. The benchmark fastest sailing between the two cities was set by the 225ft three-masted clipper Flying Cloud , which sailed around in 89 days 8 hours in 1854, a time that was unbeaten for 135 years.

Since then over 200 record attempts have been made, in everything from trimarans to maxis, yet it has never been attempted in a single-handed proa. American sailor Ryan Finn is bidding to be the first to do so, solo and non-stop.

Pacific proa

Proas have been around since adventurous island dwellers first strung cloth atop a dug-out canoe, with early versions developed by Austronesian sailors for exploring the unknown southern seas of the Indo-Pacific some 7,000 years ago.

Made up of a single hull and second ama, they are light and fast, and simple to construct. Devotees of modern incarnations of the proa praise them for their speed under minimal sail area and their ability to absorb waves with less slamming and uneven loading than a conventional catamaran. On a close reach, Jzerro can easily pass boatspeeds of 17-18 knots.

proa sailboat plans

However, the geometry of a Pacific proa (ie with a small ama to windward) does present its challenges.

In order to be able to sail with the ama to windward on both port and starboard tacks, a proa must be symmetrical both fore and aft with two ‘bows’, two lifting rudders, and a rotating mast.

On a boat the size of Jzerro , which is 36ft long, accommodation and stowage is severely limited by the single hull, and cockpit protection almost nonexistent. Attempting to sail a proa around Cape Horn, against the prevailing winds, is an extreme challenge.

proa sailboat plans

Ryan Finn says the idea of a proa adventure was what first inspired him. “The boat concept came before the route. I’ve been thinking about multihulls than can sail upwind without experiencing major structural issues, and that’s where I became aware of Russell Brown’s designs. I knew they had successfully travelled far and I realised a proa would solve a lot of the structural beam issues that big catamarans and trimarans have, since you’re not leaning on the leeward ama – the leeward ama is the main hull.”

Sailrocket set for speed record

Paul Larsen plans to break the outright world speed sailing record this year aboard the 30ft carbon fibre flier Sailrocket

Inspired by sailors like Tom Follett, who raced his proa Cheers from Plymouth to Newport Rhode Island in the 1968 OSTAR, Finn was sold on the proa concept. He bought pioneering proa designer Brown’s own Jzerro , which Brown had sailed across the Atlantic and Pacific Oceans.

Finn has been working as a delivery skipper for many years and before that competed on the Mini Transat circuit. “There was no way I’m going to raise money to race in France, I’d already attempted to do that before,” he explains. “I can never compete with their budgets, so I thought I should stop trying to play their game and just do the kind of sailing that I want to do.

“The New York-San Francisco record was very difficult and very long, and it was available, because no-one has done it single-handed non-stop before so I thought I’d give it a shot.”

Single-handed record attempts at the route have been rare: in 1989 Philippe Monnet attempted it on a Shuttleworth-designed trimaran. Monnet had to stop and restart after hitting ice, but managed to complete the voyage in 81 days. The crewed record, meanwhile, was set by the 110ft catamaran Gitana 13 at 43 days in 2008.

Despite its metropolitan start and finish points, much of the 14,000-mile route is more akin to an ocean crossing. “A lot of people don’t realise how far to the east Brazil is, it’s way out there,” points out Finn. “So to clear the eastern point, you have to go really far offshore, almost like a transatlantic, more than halfway across the Atlantic to get around that point. Then there’s potential for a lot of coastal navigation around Patagonia, and in the Pacific, it should be pretty far offshore too.”

Solo sailing mods

Although Brown had sailed Jzerro double-handed across the Pacific, Finn needed to modify the boat for solo sailing. “The biggest thing was I needed new sails and I wanted the sail handling to be a lot different.

So I’ve moved a lot of chainplates for the headsails on both ends, and added medium roller furling sails on halyard locks,” recalls Finn.

proa sailboat plans

The ‘off-duty’ rudder is lifted, here the ‘port tack rudder’ as Finn refers it. Photo: 2Oceans1Rock

Proas do not tack, instead proa sailors make a manoeuvre called ‘shunting’, which involves setting a new foresail, furling and lowering the old one, easing the main out to leeward, rotating the rig, resheeting the boom to the ‘new aft’ fitting, and raising and lowering a rudder on either end.

Finn says that the proa is not unstable during the process, however. “Because the mainsail is completely to leeward, just sort of flagging there, the boat is really settled when you’re shunting, it’s a good time to take a break – the boat parks and you can really stop.” Shunting is not, however, an easy manoeuvre to make with limited searoom.

Finn has opted for wind instruments on a static pole on the ama, rather than masthead units on the rotating rig, for simplicity. However, he points out: “Because you’re going forwards and backwards, you have to recalibrate the autopilot every time you tack. Everything has to flip 180°, so it’s kind of complicated. I’m getting used to it, but I don’t know how many proas there are sailing that have autopilots!”

Another big element that needed improvement for the record attempt was shelter. “The boat is very, very wet because it’s very light, so there’s a lot of spray. I’ve created a dodger that I can tack from one end to the other that protects the cockpit pretty well,” explains Finn. When not required, the dodger can be lashed to the trampoline.

Back to basics

Initially New Orleans-based Finn hoped that his all-American endeavour would attract sponsorship, but when little was forthcoming he decided to push on with the record bid as a low budget project, cutting his own sails, and building custom components such as halyard locks himself.

Finn hopes to inspire others to realise that adventure sailing can be affordable. “I always wanted to prove that you don’t have to have millions of dollars for a boat that’s capable of setting an impressive record,” he says.

Accommodation on Jzerro is limited within the main hull and leeward pod that extends outboard – and although Jzerro ’s ply interior was beautifully crafted, Finn describes the sink as his sole luxury. Solar panels and a fuel cell were installed for power, with Iridium GO! for communications.

Finn’s first attempt at the record began on 21 January 2021, but Jzerro sustained damage off the eastern seaboard, puncturing the forward edge of the leeward pod, and the attempt had to be aborted early on. Finn has returned Jzerro to Brown’s yard, where he’ll make repairs and hopes to resume his record bid.

“Having sailed over 10,000 miles on Jzerro , and in much more demanding conditions than I saw during this record attempt, the damage was a surprise, but also a good revelation for preparing to make another attempt,” explains Finn.

The biggest contributing factor leading up to this failure, he says, was how heavily loaded Jzerro was when he left New York, largely due to the volume of water he was carrying (he had no watermaker due to budget restrictions). Finn is now working on a major weight saving programme to reduce loads on the structure, also adding a watermaker and increasing power capacity.

 Two Proas at Once

I built my first Proa 5 years ago for testing. I was very pleasantly surprised.
The main hull I later used as the ama on my Great Proa.

My first Proa under construction...
... and under sail  

Actually, my big boat is a converted PORT MADISON PROA. There is no blueprint, only the entry in the Duckworks Magazine Design Contest #6. The construction is Stitch and glue with 6mm ply for all but the bottom which is 10mm. The rudders are outside, connected with wire ropes, and are easy to pull up. You can reach everything from the cockpit. The cockpit itself is 1m by 2m and can be removed to make transport easier   LOA - 7.5 m BOA - 4.5 m   The sail is a crabclaw, that runs on a rail. In the spring I will send you detailed photos and drawings, if everything goes well.

Here I am early in the big boat project...
... do you recognize the ama?  

There are several reasons I chose to build a Proa. Originally, I wanted to build a TIKI 26, even going so far as to buy a set of plans - without thinking where I would build it or how to transport the hulls, etc. Being a solo sailor was important to me, but this boat was a little bit too much - too big and too complicated.

Now it is getting well along

One day I saw a movie on TV about the TAUMAKU project. It has fascinated me. Some natives built a Proa without any metal parts, such as nails, screws, etc. I thought I could sail such a boat alone.

Ama/aka joint   

I looked everywhere, in books, magazines and the Internet for information about this type of boat, and thus I found the Port Madison Proa at Duckworks Magazine. In my eyes, this boat, in all ways, was the best of the bunch.

Aka lashing

I had built the small Proa in Stitch and glue construction to test the behavior of this type of boat in all situations. In doldrums as well as storm, it behaved wonderfuly and safely.

sail detail 

In spite of some resistance from my wife, I then decided to build the larger boat. I sat down and made a drawing 1/10 scale. I used the Tiki 26 construction drawings and the information on the Madison Proa to design my own boat. Due to the length of the three 6mm plywood sheets, I decided on a total length for the boat of 7.5 m. I used the TIKI's beams only bent, it was great work. For the AMA, I used the main hull of the small Proa. (I had two boats at once)

Rudder details

I deliberately moved the outside of the hull/ rudder attachement to avoid major damage and plan to keep the crabclaw rig because any boat sailing without one, in my opinion, does not deserve the name PROA.

I'm building her in my backyard.

The first sail will take place on a small lake in the Salzkammergut and if everything works, I will sail farther.  (My dream is circumnavigating Europe) A report with photos follows, as promised, in spring. Until then much needs to be done.

Praise for proa design

  • Roger Nadin
  • August 14, 2023

Roger Nadin on traditional proa design that’s enjoying a kit-boat revival

A proa design boat moored

Back when Captain Cook ‘discovered’ the South Pacific, local people were using what, to Western eyes, were unusual sailing boats.

These had twin hulls but with one hull shorter than the other.

They couldn’t be sailed into the wind and would not tack through the wind. Instead, the asymmetrical main hull could be sailed in either direction in a move known as shunting.

The attachment of the single crab-claw sail (the tack) to the hull could be moved from one end to the other.

This boat, known as a proa, is sailed so that one of the outriggers is always to windward.

a man sailing a proa design boat on calm water

Proa design: T2 proa under sail. Credit: Peter Richardson

Originally developed from a single-hull dugout canoe, the proa was changed to a fast, stable sailing platform with the addition of a single counterbalancing outrigger known as an ama.

The main, longer hull is known as a waka. From small, paddled workboats, proas grew to become stable ocean-crossing sailing craft that were key to the distribution of populations in the Austronesian and Polynesian areas.

History is filled with magnificent stories of great ocean voyages using proas and these continue in one form or another to this day.

With the digital age new proa-based ideas have come from France, the US, Poland and even the UK where proa plans can be found among the multihulls from James Wharram ’s drawing board.

Proa design pro and cons

So, what are the advantages of a proa boat ?

It’s quick and cheap to build, fast and stable, lightweight, and easily transportable; even boats up to about 18ft can be carried on a roofrack.

Its shoal draught provides access to waters other boats can’t reach and once assembled, the proa provides a comfortable, stable platform on which a standard tent can be erected.

It’s an ideal craft for ‘camp cruising’.

An additional quirk of the design is that it doesn’t have a rudder .

Instead, a steering paddle is used to power the boat when the sail is not in use. If there’s one negative about proas, it’s that they’re not very manoeuvrable.

A similar craft that actually tacks is known as a tacking outrigger canoe, and that would be a better option if sailing in enclosed waterways.

Freestanding masts: Why more cruisers should go wireless

You see a yacht with a mast, or masts held up with no rigging and think: ‘What’s going on? Why…

How do you get hold of a proa? Some yards will take commissions for proas up to around 36ft, though most modern proas fall into the smaller (16 -25ft) range and are self-built – either from plans or a kit of pre-cut parts.

A recent build here in the UK is a T2 from the New Zealand-based designer, Gary Dierking.

This strip-plank boat was commissioned by its owner to be built at The Boat Building Academy in Lyme Regis.

The owner took the opportunity to also sign up for a boatbuilding course. So – a new boat and a new skill all in one go!

There’s a very active group of proa sailors and builders in Poland.

These proa fans sail the Baltic coast and the big lakes of Poland and produce plans plus kits for boats up to 23ft.

So if you’re looking to keep the costs down and want a fast, easily transportable boat, the proa or outrigger canoe could be the boat for you.

Imagine you live in house close by the beach. The noise of the breaking swell, seagulls in the air and the salty taste of the ocean breeze will accompany you every day. Sounds great? Off course it does, at least one reason why 80% of the human population lives close by the ocean. But the dream of a place by the sea is turning into a nightmare for a growing share of the population: a rising sea level is eating up the shore lines, causing soil salination and squeezing out the freshwater lenses of islands or low lying coasts.

I didn’t thought to much about all of this until I got a job at “Waan Aelon in Majel – Canoes of the Marshall Islands” as part of an assignment for the GIZ implemented Low Carbon Sea Transport Project (LCST) in Majuro, Marshall Islands back in 2017. The Marshall Islands are a small island nation in the central Pacific between Hawai’i and Papua New Guinea. The country consists of low lying coral atolls only, with the highest elevation just a few meters above sea level. Shortly after arriving in Majuro, the nations capitol, I found the most beautiful islands I could have dreamed of, settled by wonderful, gold-hearted people. But at the same time almost every single problem humanity yet caused is present on these islands on a micro-scale: cultural damage by colonization and imperialization, high radiation level by nuclear weapons, forced migration, overpopulation, urbanization, drug abuse, plastic trash, deforestation, overfishing, coral bleach, (water) pollution and so on. But the most devastating problem for these low-lying island is just emerging: sea level rise, caused by climate change. The Marshallese people did not primarily cause any of those problems, but suffer every day. The scientists predictions doesn’t sound very promising either: a couple of decades, or half a century until the islands will be uninhabitable due to inundation and frequent floods! After the nuclear tests the population will be forced to leave their ancestors homeland for a second time – a cultural genocide.

So all hope is lost?

Not yet. The small NGO “Waan Aelon in Majel” (WAM) fights all challenges since 30 years by preserving native culture (especially boat building and sailing), offers a perspective for young people to make a living and by creating international awareness for the climate crisis.

As a child of the East-Frisian island Norderney I know the oppressive feeling of being surrounded by roaring waters during the storm season in winter since I can remember. But still it was the work of and for WAM which was an eye opener for me. Norderney and her 6 sister islands consist of fine white sand only and elevate just a couple of meters above the north sea. Without any protection around them they are as vulnerable for erosion as a sandcastle. Yet nobody at home seems to be too concerned.

Back in Germany the daily routine and all projects I previously had felt pointless compared to the real challenges of our future. Step by step the idea of combining what I’m good at (building boats and sailing) and the desire to be a part of the solution instead of the problem shaped out of the fog. Christian came back to Germany a couple of months later (he worked for WAM in Majuro, too) and was immediately hooked by the idea: the Proasis Project was born.

Every island and every shore in the world shares the same ocean with each other and is already affected by the rising sea level. Its a fight for the island I call home, for the land of our Marshallese friends and for the far majority of the human population. We can only fight (and maybe still win) it together!

The Proasis project will carry the spirit of WAM from the Pacific Ocean to new, somewhat colder waters around northern Europe. To create awareness and demonstrate an alternative way, we will design, construct and sail Proasis, a pacific based proa (outrigger sailboat, see “ What is a proa “). Proasis will be powered fossil free, simple and low cost. By using mainly recycled or degradable materials she will be eco friendly with a small footprint. At the same time, Proasis serves as the prototype for a fleet of emission-free fishing and transport craft, build by WAM as part of the GIZ implemented project “Transitioning to Low Carbon Sea Transport” in the Marshall Islands.

Our goal is to be visible on the water as an eye opener for as many people as possible, in the same way WAM has been an eye opener to us.

We will try to post an update at least once each month, so stay tuned!
