In order to predict the motions of a planing hull in waves, it is necessary to accurately estimate the force components acting on the hull such as the hydrodynamic force, buoyancy, and friction, as well as the wave exciting force. In particular, based on strip theory, hydrodynamic forces can be estimated by the summation of the forces acting on each cross-section of the hull was mathematically developed by Zarnick, and his formula had been used to predict the vertical motions of prismatic planing hulls in regular waves. In this study, several improvements were added to Zarnick`s formula to predict the vertical motions of warped planing hulls. Based on calm water model test results, the buoyancy force and moment correction coefficient were modified. Further improvements were made I the pile-up correction. Pile-up correction factors were changed according to variations of the deadrise angles using the results found in previous research. Using the same hull form, captive model tests were carried out in other recent research, and the results were compared with present calculation results. The comparison showed reasonably good agreements between the model tests and present calculations.
