The Proa File Primer

The illustrated glossary of bilaterally asymmetrical sailboats.

imageaerohydrofoil  Sailboat concept pioneered by Bernard Smith in the 1960’s and described in his seminal work The 40-Knot Sailboat. Smith’s analysis of sailboat kinetics led him to a groundbreaking design involving no traditional sail or hull, instead utilizing solid airfoils and buoyant hydrofoils, arranged in a proa-like formation. Many of today’s proa advocates credit the…

Bit & Kontell Outrigger Pocket Cruiser

Yann Quenet has come up with a design for an 18’ sailing outrigger with some features we really like for a minimal multihull pocket cruiser.

Bit&Kontell 5.50: “Not really a cat or a tri or a proa, cruise freely combining storage volumes and light, and space for a kayak or various boards.”

He’s put the outrigger ama to good use, with the daggerboard and mizzen mounted there, as well as providing a big hatch and enough volume to carry…

CHEERS poster benefit

Russell Brown at Port Townsend Watercraft is now offering posters of CHEERS to benefit the Newick family. It is a painting by Bruce Alderson depicting the proa in action, racing singlehanded across the North Atlantic in 1968. This is my favorite image of the most famous modern proa in history. The posters belonged to the late Richard C. Newick, and are in limited supply. Find out more here.

Proa File forums spring update

Photo: Skip Johnson

Spring is in the air here in the northern latitudes - the ice is melting, trees are budding, and the forums are becoming more active. Some recent threads of interest:

Bionic Broomstick: Skip launched his 14’ proa on March 13 at Lake Somerville, Texas, for a successful first sail (nothing broke!). The boat is highly experimental and features a buoyant “floil”, stem mounted rudders and a cambered panel staysail. The…

Proa File forums winter update

The Proafile Forum has some interesting threads we’d like to point you toward if you are so inclined. This is just a teaser, head to the forums to check it all out.

Skylark: A Dymaxion Yacht. Your editor asks the question: “What would Bucky Do?” and finds an enclosed teardrop, aluminum, wingsailed proa in the answer.

Wingsails on Proas! Inspired by the circular cam of Peter Worsley’s wingsails, members are hard at work adopting the…

Outrigger Junior from CLC

Quick on the heels of the proa Madness, John Harris of Chesapeake Light Craft has announced the new Outrigger Junior as the latest member of the CLC stable. A 15’ plywood stitch-n-glue sailing outrigger, OJ is car-top-able, beach-able, tack-able, build-able and afford-able, so maybe not so crazy after all. Special thanks to Proafile reader Brian P. for the submission!

Inspired by Warren Seamen’s Malibu Outrigger, this boat is truly a…

A Cunning Plan

Paul Bieker has announced that study plans are now available for the 32’ Jester class proa - a collaboration between himself and Russell Brown. This design has already got the interest meter pegged in the forums and this will only turn it up to eleven.

50’ Proa by Julien Marin

This intriguing Pacific proa is from the board of French naval architect Julien Marin. LIttle is known about the design except it is 50’ long and the cassette rudders sit in rotating cylinders, permitting an adjustable draft while maintaining rudder control.

Wind Powered Food Truck

Not multihull or America’s Cup, but probably the most inspiring sailing story of the year:

“…Seeking a more sustainable way to get his grain to market, the Vermont farmer Erik Andrus conceived the Vermont Sail Freight Project to find out if this model could work again today. In April, he raised more than $15,000 on Kickstarter to build a 39-foot-long plywood sail barge named Ceres (after the Roman goddess of agriculture)...

The boat,…

RIP Richard Newick

Last night, Richard C. Newick, one of the great multihull pioneers, passed away. The father of so many brilliant designs, but to a proa obsessed mind, he stands apart because of CHEERS, the “giant slaying” proa of the 1968 OSTAR.

Dick often talked about how in a previous life he must have been a Polynesian outrigger canoe designer, and perhaps that is the best explanation for his gifts. We can only imagine what sort of vessels he…
