Large hard-chine monohulls have been widely used recently for commercial purposes. However, their resistance characteristics and, in particular, their seakeeping characteristics can not be theoretically predicted. To partially alleviate this problem, and on the basis of comparative testing with competing hull forms, a double-chine, wide-transom with warp hull form, with a L/B ratio of 5.5 was designed. Using this hull form as a parent, two more were designed with L/B = 4 and 7, to form the nucleus of a new systematic series. Models of the three hull forms have been tested for resistance and seakeeping in head seas. The seakeeping results for all hull forms, presented in the paper include: pitching motion, C.G.(Centre of Gravity) acceleration and mean added resistance for Fn (Froude number) 0.34 and 0.68, in seven sea states.
