THE WAVE HEIGHT UNDER A HIGH LENGTH-TO-BEAM RATIO SURFACE-EFFECT SHIP IN REGULAR WAVES

The Froude-Kryloff hypothesis stating that a wave field in the region of a floating body may be assumed to persist as if the body were transparent to waves has been examined for a high length-to-beam ratio surface-effect ship. The wave amplitude has been measured at several points within the cushion area of a surface-effect ship model free to heave and pitch, in regular head waves. Significant modifications of the encountered wave field were observed at certain wave excitation frequencies. It is not possible, however, at this point to differentiate the sidewall wave generating influence from the effect of the unsteady pressure field in the cushion area of the surface-effect ship model tested.
