When Cats Fly

Continuing in the ‘Old School’ vein, here is the 1924 Savoia-Marchetti S.55 - a twin-hulled flying boat that set 14 world records for speed, payload, altitude and range. “The most incredible serial-built flying boat of the Interbellum.”

Designed by Alessandro Marchetti, the S.55 achieved great fame through spectacular long-distance flights: Lieut-Col the Marchese de Pinedo flew the Santa Mariafrom Sardinia to Buenos Aires and... Read on »

CataProa - a micro multihull by Bernd Kohler

Modern multihulls got their start in the 1960’s by being relatively cheap and embarrassingly fast when compared to the monohull sailing yachts of the day, and so attracted an enthusiastic following of iconoclasts. Since then, multihulls have cruised relentlessly up market - leaving the “cheap” aspect in the wake of history. Bernd Kohler is one multihull designer and pioneer who still appreciates the virtue of thrift, and his... Read on »

Russell Brown Refits a G32

Russell Brown of PT Watercraft is refitting a venerable Gougeon G32 in his shop this winter, and best of all, he’s blogging all the details! Sort of like hanging out in his shop, but a lot better because he’s still able to actually gets stuff done. If you’ve ever wanted to see how carbon fiber, epoxy and a vacuum bag all come together to make multihull magic (and who hasn’t?) then head on over to gougeon32.blogspot.com.

Gold Coast launches new Bieker 53 cat

Gold Coast Yachts of St. Croix, USVI, have launched the new Bieker 53 performance cruising catamaran. The polarizing aesthetics aside, we are very interested in this build. The curved boards are a moderate use of hydrofoil tech that is extremely promising. Unlike the fully flying Gunboat G4, FUJIN’s foils do not lift the hulls completely free of the water’s surface. The boards augment righting moment and pitch stability, making the... Read on »

The Flying Boat

Advanced Aerodynamic Vessels of Nantes, France, aims to improve the speeds of passenger vessels by harnessing the flow of apparent wind. The catamaran employs planing stepped hulls similar to a seaplane, but the resemblance to a flying machine doesn’t stop there. The central bridgedeck is carefully shaped into a wing that creates aerodynamic lift and reduces both displacement and drag:

The operational speed of today’s small... Read on »

Multihulls in the Race to Alaska

The R2AK starting gun goes off in less than two days: June 4, at 5:00 am. Among the fleet of 56 boats due to depart Port Townsend on Thursday morning, nearly 50% are multihulls. Point Hudson is beginning to resemble Plymouth during the OSTAR and St. Malo during the Route du Rhum! The harbor is filling up with the coolest multihulls we’ve ever seen, many purpose built for the race. Not to say that there aren’t very interesting monos... Read on »

Trailerable Brine Shrimp in California

Though it doesn’t say in the ad, this 23’ folding catamaran is a Thomas Firth Jones designed Brine Shrimp. Built in 2000, the boat appears a bit rough but the nice thing about plywood boats is that there isn’t anything that a little time and basic wood shop skills can’t fix. The sale includes trailer, sails and 4 hp outboard (that needs a tune up). Find it here on Craigslist in Vallejo, CA for $6000.

From the designer:

The Sultans of Wing

Just to prove that we aren’t complete small boat snobs over here at Proa File, here’s a yacht that’s well over our usual cut-off in length and opulence. This is the sort of thing that Nigel Irens Design has been up to lately, and we have to say it: the A-65 is probably the loveliest luxury sailing catamaran launched since the turn of the century.

The challenging brief from a client in the Emirates was to design a truly... Read on »

Water Bug - an SUV catamaran powerboat

The Water Bug is an experimental catamaran motorboat designed and built by Russell Brown of Port Townsend Watercraft. It uses a pair of Tornado catamaran hulls as the base, and is extremely efficient, getting 20mpg at 11 knots, while loaded AND pulling a dinghy. Russell uses it like a water-born SUV - hauling stuff and going camping. The “car” is plywood/epoxy construction, it was drawn on the back of an envelope so there are no plans.... Read on »

James Wharram Designs Mana 24

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,... Read on »
