Hulls that are intended for Passagemaking will most likely be of the round bilge hull form. It is possible to design a semi-displacement round bilge or round chine hull but the type is more suited to the chine hull configuration. Round bilge can be used for any displacement type hull especially those that are to be used for long distance voyaging. One area we are exploring is the design of steel radius chine power boat hulls; our ideas are at the developmental stage and I believe that this idea is worth further investigation.
