Abstract
The technical memorandum describes the FORTRAN computer program HEWDIP (HEadWave DIffraction Pressure), which calculates: (1) the pressures induced by the incident and diffracted waves on the hull surface, (2) sectional heave exciting forces, and (3) wave amplitudes along the length of the hull of the advancing ship in regular head waves. The hull is assumed fixed at its equilibrium position and translates at a constant forward speed. HEWDIP approximates the solution of the linear three-dimensional boundary-value problem for the diffraction potential by slender-body theory and the method of matched asymptotic expansions.
