HULL-WAVE IMPACT LOAD ON HIGH-SPEED MARINE CRAFT.

Abstract

A theoretical method for estimation of the bowimpact force of high-speed marine craft on regular waves is presented, based on the strip theory and the concept of virtual mass. Numerical results are obtained for two models, one with constant deadrise and the other with varying deadrise. Experimental studies on impact lift, drag, pitch moment, and phase angle are reported, for the same models under various wave conditions. The theoretical results for impact lift are found to be in good agreement with measurements, except in the case of very high and steep waves. (Author)
