Abstract
A fully 3-D Rankine panel method in the frequency domain is validated for local pressures and global rigid-body motions. The method is linearized with respect to wave amplitude. The steady flow contribution is captured completely by solving the fully nonlinear wave-resistance problem first and linearizing the seakeeping problem around this solution. Motions are in good agreement with experiments, but this is also the case for a simple strip method. Local pressures are much better predicted than by the strip method.
