Resistance and Seakeeping Model Tests of Two U.S. Coast Guard Notional Designs of 110 FT and 120 FT WPB Hulls.

摘要

The research results presented in this report are concerned with the performance and seakeeping characteristics of two Notional WPB Designs, the 110 FT WPB and the 120 FT WPB. Model tests of the two hulls were conducted in calm water, in regular waves at 10 knots, in wave heights of 12.5% and 25% of the beam and in irregular head seas having significant wave heights of 40% and 60% of the beam at speeds from 25 to 70 knots. Spectral analyses were performed on the motions and accelerations in irregular waves and the results are tabulated and plotted, including the 1/c octave RMS accelerations. Resistance data in calm water and waves were scaled to full size and the predictions are tabulated. Planing boat motions, Planing boat performance, WPB Notional hulls, Planing hulls.
