The most important catamaran design hull shape factor, is the prismatic coefficient (cp). this is a measure of the fullness of the ends of the hull. instinctively you might think that fine ends would be faster as they would “cut through the water better”. but in fact you want a high cp for high speeds.. 18m cuising catamaran wavescalpel cad animation solidworks hull shapes and outside view title: senbazuru & laid back guitars kevin macleod (incompetech.com). In addition to maximizing stability, the widest possible hull spacing was sought in order to help alleviate a common catamaran wake phenomenon. the two inboard bow waves converge at a fixed distance aft of the bow, proportional to the cutwater spacing, (the waves vee angle is a constant)..
