WebTow tank testing of high speed planing craft differs from traditional displacement hull testing in several aspects, even when the objectives are similar. While the sinkage and trim of a displacement ship does change with speed, the changes are relatively small and do not result in large changes to their waterline length and wetted surface area. Planing craft, …
