Heave and Pitch Regular Wave Exciting Forces and Moments Acting on a Small Waterplane Area Twin Hull.

Abstract

Experiments were carried out to determine the hydrodynamic forces and moments acting on a model of SWATH I (Small Waterplane Area Twin Hull) design in regular head waves at several forward speeds. Presented in this report are the heave exciting forces and pitch exciting moments on the model due to waves. The results showed force and moment linearity with wave height and a force and moment dependency on wave encounter frequency and speed. (Author)
