A simple and convenient numerical method for the prediction of the motions of fast displacement vessels is presented. It is based on the so called two and a half dimensional (2 1 /2 D) theory where the three dimensional (3D) free-surface condition is retained but the control equation and body surface condition are treated as two dimensional (2D). The 2D transient free-surface Green function is used to formulate the integral equation on the body surface. Numerical predictions are compared with experimental results associated with a NPL catamaran ship and a trimaran ship, as well as the theoretical results derived by strip theory. In contrast to strip theory, it is found that the proposed method produces satisfactory predictions of the motion response characteristics of multi-hulled vessels at high forward speed in head sinusoidal waves.
