With the computerprogram “Trial” calculations have been carried out to determine the seakeeping qualities in head waves of systematically varied shipforms.

    These ships were derived from the well-known “Todd-60” series.

    The following varied parameters show in succession of importance the influence on ship motions etc.: ship-length, speed, forebody section shape, block-coefficient, position of the centre of buoyancy in length, radius of inertia. Pitch especially decreases with ship-length, while heave increases with speed. For V-shaped forebodies the heaving motion is strongly reduced, while there is an advantage in added resistance up to a certain ship length, which depends on speed and sea-condition. Above this length a small profit for U-shaped sections has been established with respect to the added resistance in waves.
