ABSTRACT:
The invention is directed to an improved multihull vessel for enhanced seakeeping and reduced hydrodynamic fluid resistance and a method for minimizing the wavemaking resistance of multihull vessels. Lower wavemaking resistance is realized while maintaining the advantageous seakeeping characteristics of small waterplane area multihull vessels. By the proper arrangement of slender, tapered hull elements, the present invention produces favorable wave interference effects and smaller surface wave disturbances resulting in lower wavemaking resistance. A tapered hull design provides a small waterplane area for enhanced seakeeping while producing smaller surface wave disturbances and reduced hull interaction resistance due to the lack of surface discontinuities. In addition, proper arrangement of hull elements provides favorable wave interference.
