Design #96 -- 60 ft. LOA Cruising Catamaran
It's not everyday we get opportunities to step outside our forte of semi-modern / modern classic sailboats. Now, at the end of a development process, our 60 ft bi-plane catamaran concept can enjoy a little exposure. "This is a strong example in our abilities as designers to span our work between alternate sailing universes, and to shape our clients goals and dreams into something viable for performance and budget that suits the mission."-- says Paul Waring.
Scientific data confirms our design is sound, the mission to reel off the miles over long sailing passages at speeds in the mid-high teens makes sailing come first, like all our boats. In VPP and CFD studies we've conducted, the data show how this unique sailing platform is capable of equal, or better in most cases, performance results when compared to her conventional single-masted sloop counterpart. At this preliminary stage, we have realistic budget framework, we have beat assumptions in original weight goals, and we have exceeded all preliminary targets for performance characteristics. Have a look at the design brief....
Distinguished design for world-class cruising
For sailing inshore and offshore with equal ease, comfort, and performance.
Distinctive styling by SWYD.
Capable ocean-going safety and user-friendly performance sailing.
Generous interior space and comfortable cruising.
Conceived with a goal of world cruising to destination in the tropics and ranging to areas in mild arctic latitudes, the cat shall be capable of sailing in all kinds of conditions. Inspired by sailors, the design is focused on family living and connectivity, yet geared for serious adventurers. At the heart of this design beats a measured rhythm for life on the water, enjoyment of the outdoors, upon a platform for a light and sporty sailing machine.
The Cat: Crisp lines and efficiency in superstructure. Distinguished from the rest of the pack. Layout provides safe sail-handling, comfortable movement on deck, and delivers pure enjoyment of the elements.
The cockpits: An aft lounge area is palatial and comfortable, separate from all the work. The forward cockpit is all business, where the sailing gets done -- arranged with port and starboard line management stations to hoist, reef and trim the mains.
The sails: Squared-headed, efficient and powerful. Easily managed and trimmed from the forward exterior sitting area -- push-button functionality for all line handling along with halyards, mainsheets, reefs and "snotters" all micro-managed from the cockpit.
The rig: Un-stayed, tandem cat rigs in each hull, each controlled via wishbone boom single mainsheet. A light air/downwind spinnaker rigged from a mast-head for optimal sailing. Option for conventional single mast and sloop rig configuration rigged with permanent stays also available.
The mission: A sailing platform founded on balance for simplicity, practicality, performance and cost.

Not if the boom length is less than the distance between the masts, in which case it will be a delight to sail downwind.What is it? A cluster fuck downwind.
I 100% agree. However, only 28' beam on a 60' biplane cat? My 36' biplane cat has 24' beam, and MUCH shorter masts.Not if the boom length is less than the distance between the masts, in which case it will be a delight to sail downwind.What is it? A cluster fuck downwind.
Either wing and wing or both sails on the same side. No poles, no extras to hoist and lower in squalls, no extra sails to look after, no fear of crash gybing and hitting the shrouds, no wear from the sail rubbing against the shrouds and nothing to worry about, maintain or replace in the standing rigging department.
If the breeze does increase beyond comfortable, ease the sheets until the sails are streaming downwind, over the bows. They can then be easily reefed, and just as easily rehoisted when the wind drops.
A far better cruising rig than a conventional stayed sloop, especially one with a 3 stay set up.
Because one of the most common mistakes is to overload a cat. Long ends with no place to put 'stuff' ensures that the owner will have to work much harder to put extra crap onboard. It means the boat is really, effectively a smaller boat but one that has lwl length for higher speed potential (and better aesthetics). An owner who has a custom cat designed and built also isn't worried about paying the difference in the extra slip costs either.Not sure why they would devote about 1/3 of the LOA to stairs and a place to hang the RIB with a tiny stern deck.
