DYNAMIC WATERLINE SEAKEEPING PREDICTIONS FOR A FISHING VESSEL

This report examines the use of a dynamic waterline for strip theory motion computations for a full-hull fishing vessel. This vessel exhibited considerable trim, sinkage, and bow wave at high speed. Because of this, it was thought that the use of an experimentally determined high speed waterline could improve prediction accuracy. It is shown, however, that no improvement was obtained. It was concluded that computational errors introduced by the dynamic waterline were negligible compared to errors introduced by the full-hulled vessel's violation of strip theory assumptions.
