The paper will present the results obtained from the experimental tests, performed in the towing tank of the University of Trieste, on two fast fishing vessels models, having the same main dimensions, ratios and coefficients, but different body plan. The hulls were designed by using hard-chine type and round bilge sections respectively. The hull performances were compared as regards the towing and wave pattern resistance, the wave generation, the transversal stability and the rolling motions in regular beam waves. The experience confirmed that the hard chine sections reduce the rolling motion but slightly increase the wave and towing resistance, as reported also by other who analysed separately the two aspects. In this case, simultaneous comparisons of the different phenomena allow a better evaluation of the two hulls performances.
