SEAKEEPING FOR DESIGN: IDENTIFICATION OF HYDRODYNAMICALLY OPTIMAL HULL FORMS FOR LARGE HIGH SPEED CATAMARANS

Two highly relevant questions pertinent to the design of high speed craft are addressed. What is to be understood by "forward speed analysis", and how does that understanding influence the seakeeping prediction methods used in investigating high speed craft? Having developed a strip-theory based design methodology for both monohull and twin hull (catamaran) forms to identify hydrodynamically optimal forms (in the context of seakeeping for design), how should confirmation of the identified optimal hull form be provided? Having addressed these questions, results for a large high speed catamaran hull form are presented and discussed in the context of 2D vs 2D hydrodynamic analysis, the forward speed corrections, and the effects of inclusion or exclusion of demihull fluid structure interaction effects. Some indication of ongoing research is provided with the conclusions and final comments.
