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.

Regardless of the vessel subs excepted. A discussion about bow shapes in particular the way the reverse bow is becoming a dominating design trend in modern catamarans and trimarans. It is a geometry-stabilized craft deriving its stability from its wide beam rather than from a ballasted keel as with a monohull boat.

Ultimately the bow should have an increasing buoyancy reaction as it is immersed if it is expected to lift the vessel above the waves volume below the immersion line is already immersed and effectively neutral. Richard Woods catamaran designer and sailor talks to us about bow shapes on cruising catamarans and why bow shape should be an important consideration to buyers of catamarans. In the third part of our series we talk again to Antoine Richer the Naval Architect at Seawind about how bow shape hull volume and freeboard affect the pe.

Will exceed the ability to keep the bows out of the water and the boat will pitchpole. Instinctively you might think that fine ends would be faster as they would cut through the water better. 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.

Many people think you need a modern design with vertical bows and rounded decks for high speed. Displacement cats do require more care to design and more rigorous engineering to perform as well as they do.

But in fact you want a high Cp for high speeds. The design of an Incat Wave Piercing Catamaran WPC is a constant evolution. Variations of reverse bows are in many new performance cruising designs by reputable performance cat builders like Catana Alpha and Gunboat but the design is not quite as popular for regular cruising catamarans.
