It will reflect the catamarans resistance to tripping.

Catamaran design ratios. So a multihull should be at least 061 and a heavy displacement multihull a bit higher still. Heavy and doesnt let the water throughcan trip in large ocean wave surfing situations Accommodations spread into the ends. Some skimming dish racing sailboats also have LB in this range.

Fountaine Pajots Lavezzi 40 designed by JoubertNivelt in 2003 has a DL of 99. Their wide beam gives them more initial stability so that they can fly larger sails. The Lock Crowther-designed Catana 44 first built in 1992 was one of the earliest fast French production boats to hit the market.

Safety reliability performance comfort and pleasure are the keywords throughout the design of an Outremer. With such wide aft hull ends the boat will have a lot more buoyancy than I need. BeamLength ratio 58 Static stability about 55 knots.

Typically cruising catamarans have a beam-to-length ratio of roughly 50 meaning a 45 long cat will be about 22 wide. This design also included a modern mast for better performance. Low aspect ratio keels are very popular on cruising catamarans as they offer a good compromise between easy sailing and cost while also protecting the hull from possible grounding damage and usually add to the load carrying potential.

5 its own center of gravity and the added volume of seawater acts in exactly the opposite direction through the CF and through the CG of the weight you added. Finer hulls are more efficient at high speeds but as weve just seen suffer from more WSA and so for normal cruising catamarans in average conditions a ratio of 111 - 131 seems optimum. A Catamarans Power to Weight Ratio or Sail Area Displacement Ratio SAD SA Disp 64 23 This ratio is an indicator of how much sail area a catamaran has relative to its displacement.

Two models of asymmetrical catamarans namely Inboard Asymmetric and Outboard Asymmetric catamaran hull forms were created from the existing S-NPL series mono hull model 4b with two different separation ratios sL of. Wider construction makes her heavier narrower makes her carry less sail. However the key to Catamaran design is you need a higher Cp if you want to sail fast.
