The new WindRider Rave V hydrofoil trimaran
WindRider has announced that it is re-entering the sailing hydrofoil market with a new 17’ design that is aimed at overcoming some of the chief limitations of the type, such as being a pain in the ass to trailer, rig, beach and sail.
WindRider and their design partners developed the original concept of bringing foiling or “flying on the water” to the everyday sailor back in 1998, well…

The crab claw as an ideal wind-electric hybrid yacht rig
Way back around the turn of the century, there was a lot of excitement about the potential of the native Pacific island canoe rig, often called the “crab claw” sail, so called because the plan form resembles the claw of a crab. The rig has some serious advantages, see here and here, but also some serious limitations, the primary one being that it is not as weatherly as a modern…

When sheer efficiency is required, it’s hard to beat a multihull. The trimaran configuration is gaining traction in open ocean rowing events and according to proponents, the tri has some considerable advantages over monohulls. Here are a few that have crossed the desk recently.
Samson is a two-position rowing machine designed to make the 3800 mile (6,116 km) Atlantic crossing from New York to Paris. The brainchild of…

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, giving…

Long time Proa File contributor Chris Ostlind is working up a new ultra-light, hybrid human/wind powered tri based on an A-Class cat hull. Now that’s what we call recycling. Chris says:
I’ve been pretty much out of the design arena for a little over two years now, so I was excited when I was asked to develop a set of amas for a fast hybrid function boat being built by my friend and multihull guru, Mike Leneman. Mike’s boat is based on…

Paul Bieker has announced this interesting new design on the Biekerboats blog. The foils resemble what is quickly becoming the standard on high performance race boats such as the A-class. We don’t think the B53 is intended to completely fly both hulls with this set up - the foils reduce displacement and provide dynamic stability.
Introducing the B53 high-performance cruising cat, just beginning construction at Gold Coast Yachts in the…

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…

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…

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.
