Abstract:

A six degree of freedom mathematical model of an assault boat landing on and retracting off a sloping beach through surf is developed based on both theoretical and experimental results. Included are the effects of wave refraction, winds, shoaling breaking and wave run-up on the beach. Control forces and moments resulting from the coxswain ability to alter the throttles and rudders are also included. This report is to serve as a basis for the development of a real time assault boat simulator for the training of coxswains.
