The most important thing for the catamaran is to carry the sails in the design conditions.

Catamaran hull design formulas. However the key to Catamaran design is you need a higher Cp if you want to sail fast. The design exercise that led to the offshore capable Antares 44 had to address the needs of a US catamaran market concentrated on the east coast and Caribbean zones renowned for their coastal cruising opportunities. So all multihulls should have a Cp between 061 and 065.

214 Spray Resistance. Design Specifics the SPEED. Successful designs are ones that work in every situation not just.

It is however expected that since the given hull shape is semi-displacement and the speed range is not very high this is not expected to be a very large component. Loaded displacement mass in kgs. So a multihull should be at least 061 and a heavy displacement multihull a bit higher still.

Near six the catamaran has a modern sandwich construction. Obviously this formula doesnt apply to catamarans. In the next formula 2 is for two hulls and 1025 is the density of sea water kgm3.

Also in cruising catamarans the hulls are tied together with an accommodation deck suspended above the waves. Prismatic is a secret and will vary based upon design principles. When planing a monohull will exceed its hull speed.
