DETERMINATION OF SIZE OF STABILIZING FINS FOR SMALL WATERPLANE AREA, TWIN-HULL SHIPS

A theoretical approach for determining the size of stabilizing fins desirable for SWATH 4A and SWATH 4B models is described. Determination of fin size is made on the basis of retaining pitch stability for high speeds as well as augmenting the heave and pitch damping for motion in waves.
