The Prismatic Coefficient Cp a measure of how full the ends of the hull get is the most essential design hull shape factor for any catamaran. Hull performance can be influenced by many aspects but a good hull design always results in excellent racing performance.

The deep-V hull was developed in the late 1950s and proved to be optimal for high-speed offshore vessels with transom deadrise of 18 to 24 degrees.
