Trim and Sinkage Effects on Wave Resistance with Series 60, CB=0.60.

Abstract

Resistance experiments with Model Series 60, block coefficient (CB) = 0.60 have been carried out with the model free to trim and sink and with the model fixed at zero trim and sinkage. The measurements include wave profile along the hull, sinkage and trim, wave resistance, and total resistance. The difference in the measured values for the two experimental conditions is assessed and a comparison with calculated results is made. Discrepancies between the measured and the calculated values indicated that the linear potential-flow theory used for the calculations needs to be modified in order to predict the wave resistance, trim and sinkage, and wave profiles correctly.
