Performance of High-Speed Naval Vessels. Part III: Effect of Ship Length on Seaworthiness Characteristics.

Abstract

This report presents the results of a study on the effect of ship length on seaworthiness of destroyers. This study was made for five high-speed hull forms varying in length from 200 to 800 feet. Significant amplitudes of pitch, heave, and bow motion relative to waves were computed from experimental data in various sea conditions, together with the frequencies of occurrence of bow emergence and deck wetness. It was found that pitch and heave motions improve considerably as ship length increases whereas bow motion relative to waves shows little change. The frequencies of bow emergence and deck wetness decrease significantly as ship length is increased. This is primarily due to the increase of draft and freeboard rather than to reduced motions for longer ships. (Author)
