Abstract : Comparisons of analytical and experimental response amplitude operators (RAOs) for a CVA 68 ship model are presented for pitch, heave, and several relative motions in head seas at 5, 10, and 20 knots. The experimental results are developed from regular and long crested irregular waves obtained from a free running model experiment conducted on Carriage 2 at the David W. Taylor Naval Ship Research and Development Center (DTNSRDC). The regular wave experiments were conducted in wave steepnesses ranging from 1/40 to 1/90 and the irregular wave experiments were conducted in representative State 6 and State 7 Seas generated in the Carriage 2 facility.
