Prediction of the Swamping Tendencies of Recreational Boats.

Abstract

Seven small recreational boats were tested to obtain heave, pitch and relative transom motion RAO curves in regular longitudinal waves. This data was needed to determine the feasibility of making mathematical simulations of swamping tendencies using linear strip theory, and, in a few cases, a 3-D motion theory. The probability of swamping of the boats was calculated for seven sample severe wave conditions. The boats included two jonboats, a dinghy, runabout, skiff dory and a half-scale model of a jonboat, all in a number of asymetric loading conditions. The motions were found to be linear. The strip theory was found to be unsuitable for the boats. The probability of swamping was found to be high indeed. The 3-D theory yielded promising results, but more research is needed to establish its suitability for the boats. (Author)
