The purpose of this paper is to provide additional information relative to the problem of designing efficient antipitching devices. The results of seakeeping experiments are presented for a model fitted with several alternate designs of fixed bow fins. The bulk of the experiments is concerned with the effects that fins of different aspect ratios have on the pitching and heaving motions, the phase angles between pitch and heave, the vertical accelerations, and the speed reductions in waves. Results also are presented showing the effects on pitching of fin area and of fin-tip fences.
