Models of four Cape-Island style, and one Maine-type inshore fishing vessels were towed in calm water in the Centre for Marine Vessel Design and Research's (CMVDR's) towing tank at speeds up into the preplanning regime. The vessels have some of the characteristics of high speed displacement/semiplaning hulls, but are more typical of displacement hull design in other respects. Full scale resistance, sinkage, and trim characteristics were established at several LCG's and displacements. The data were compared and non-dimensional resistance curves plotted. An attempt was made to graphically 'collapse' the resistance data to a single line, and in so doing it was found that the resistance depends strongly on displacement and waterline length to beam ratio. Regression analyses were performed on the data at several speed ranges separately for the purpose of producing resistance prediction equations. The results are compared against published material.
