The beam of a sailing catamaran is a fundamental thing.

Catamaran beam design. Andrew decided on this move away from more traditional fishing vessels as he suffered with a bad back and legs which affected his balance so he wanted to improve life at sea with a vessel which offered far greater stability and reduced. Usually the waterline dimensions LWL and BWL are used for monohulls or for a single hull of a multihull. A word of caution.

Designers strive to compromise hull fineness ratios place heavy weights towards the CG Center of Gravity and engineer hull and overall beam to achieve a seaworthy balance which is safe yet provides ample liveaboard. 3The sliding beams are then pinned in place for trailering and the forward beam tube is bundled with the main sail and boom. It primarily depends on beam and individual hull buoyancy for stability.

Catamaran stability is a function of beam and buoyancy so light-weight strong construction which translates into buoyancy is a good thing. So a 45-ft long catamaran will be about 22-ft wide providing a very stable platform. Design Catamarans is run by Andrew Craig who had his own first steel catamaran Gemini built in 1989 as a commercial fishing vessel which he skippered.

Make it too narrow and she cant carry sails enough to be a decent sailboat. The hulls are roughly 81 length. Wharram designs are based on years of practical hands-on experience of building and ocean sailing catamarans.

As discussed previously the standard Neo 21 is designed to use the rig 230 sq. Make it too narrow and she cant carry sails enough to be a decent sailboat. Beam of sailing catamaran The beam of a sailing catamaran is a fundamental thing.

So if the righting moment is greater than the capsizing moment the boat stays upright. Good stability in a catamaran is when the righting forces and healing forces are in balance. Instinctively you might think that fine ends would be faster as they would cut through the water better.
