Abstract

This paper deals with the hull form development procedure for the twenty-passenger class Wing-In-Ground ship. Two planing hull forms with the transom stern were proposed and towing tests were performed. The length-breadth ratio of hulls is 6.375 and transverse dead rise angle at midship is twenty degrees. The resistance and running attitude were measured and the feasibility is checked for the proto type hull form of the twenty-passenger class WIG ship. Measured results show the reasonable resistance performance and stable running attitude so that the proposed hull forms are reasonable. The hull form optimization in waves will near future work because of the added resistance due to high take-off speed.
