Proa Luca Antara nearing completion

Luca Antara is a new 20m (65’-6”) proa nearing completion in Sagres, Portugal, and will be ready for sea trials early 2015, according to the owner and builder, Robin Warde. The hulls are strip-planked western red cedar sheathed in fiberglass both inside and out, with extra carbon fibre strengthening where required - mostly around the masts - but also around the beams. Most of the rest of the boat is built of foam. She features a... Read on »

Proa File forums to close

Here ye, here ye! The Proa File Forums will be closing down at the end of August.

There are several reasons, but the most pressing is your editor’s time constraints. The forum is in a constant state of need and repair. I use the forum package from Expression Engine, which is the CMS I use for the rest of the site. It is buggy, outdated, not responsive with phones or tablets, and is apparently no longer being updated. This is their... Read on »

Navy wingsail tri up for auction

As part of a government liquidation, the U.S. Department of Defense is auctioning off a 50-foot sailboat to the highest bidder.

But this vessel isn’t what you’d expect from a former Navy craft. The three-hulled, high-performance Contour 50 boat, which is now in Harbor Island, was used for “experimental training and recreational purposes,” according to Liquidity Services, Inc.

Built in the mid 2000s, the craft has undergone... Read on »

Wharram Tiki 26 on Orcas Island

The Wharram Tiki 26 is a true micro-multihull cruiser. It features the now classic Wharram attributes of plywood/epoxy construction, deep V hull, no keels or boards, lashed beams, open and high bridge deck, and the Wharram “wing sail” sloop rig. The design is probably the most popular of all Wharram’s boats, and several examples have crossed oceans in safety. Find this one here on Craigslist in Deer Harbor, WA, for $6000. If the boat... Read on »

Proa Rig Options: The Sloop

The sloop is the rig of choice on 90% of all modern sailboats. Why not on proas as well? Here’s why.

Rigging a proa as a sloop is a true blending of East and West. The proa is considered the pinnacle of Pacific canoe design, and the sloop is often considered the finest invention of Western "yachting". Brilliant in their own context, what happens when we creatively recombine their DNA?

First consider the sloop. Beautiful, efficient,... Read on »

Proa Rig Options: Gibbons Rig

The story of this rig begins in Hawaii, with Euell - “Have you ever eaten a pine tree?” - Gibbons, a half century ago. Now, thanks to a renewed interest in proas and the easy flow of information on the Internet, the rig has received some new attention, and looks to become a very good proa rig indeed.

Writer and naturalist Euell Gibbons was living in Hawaii and dining on the jungle flora and fauna in the 1950’s. He soon realized that... Read on »

Alain Thebault Interview

This is a nice interview of L’Hydroptere skipper Alain Thebault by CNET’s Molly Wood. L’Hydroptere is a member of a very exclusive club: “Former holders of the world sailing speed record”. Unlike most record holders, the flying hydrofoil trimaran is not limited to shallow and waveless speed traps, but is open ocean capable. Highlights include photos of Alain’s early scale models that he built as a teenager.

This post is also a test of... Read on »

Proa Rig Options: Bolger Rig

John Dalziel gives a summary of his series of experiments on his proa C. L. Brock with a Bolger-type rig. Note: Frequent references are made to Philip C. Bolger’s proa "cartoon", which first appeared in an issue of the late Small Boat Journal, and was later published in Boats with an Open Mind; International Marine, 1994.

The Bolger proa rig echos the unique symmetry of the proa: the airflow reverses direction during a shunt, just... Read on »
