In this report several different results in the theory of ship motions are presented. Some of the results express certain physical quantities in terms of other such quantities, while the remaining results are in the direction of computing physical quantities by solving boundary value problems. The following results are of the first type 1 KramersKronig relations with forward speed and cross-coupling and 2 Impulse response in terms of force coefficient for simple harmonic motion. As work of the second type the authors present a numerical approach which seeks simplicity by avoiding integrations over curved surfaces and approximations to or representations of curved surfaces.
