Popis:	When a ship is advanced in a seaway, she usually loses in speed compared with the case in a calm sea under the condition of constant output-power of the main engine. In this paper, a method is presented to evaluate the propulsive performance of the ship by using the calculated results of the heaving and pitching motions in the case where the ship moves head on into regular head waves. The relation between ship speed, the rate of revolutions of the propeller and the delivered horse power are shown in numerical examples.
