THE EFFECT OF LENGTHENING OF A FISHING VESSEL ON ITS SEAKEEPING PERFOMANCE

The seakeeping performance in head seas of a series of four fishing vessel hulls is investigated. The parent vessel of the series is a modern Norwegian fishing vessel of 19.80m (LOA) which is lengthened in three different ways. The seakeeping performance is determined by model tests carried out both in regular and irregular waves. The irregular waves represent sea conditions typical for the North Sea/Norwegian coast. The main seakeeping responses (heave, pitch, accelerations) and added resistance are presented and evaluated both in dimensional and nondimensional form. Finally, the relative magnitude of the responses is related to hull form parameters by the method of Bales/van Wijngaarden, and the relative importance of the parameters is discussed.
