Simulation Fridays S07E03: Boat Hull Planing in a Virtual Water Tank 

A planing boat at speed rides on a small and constantly shifting wetted patch of the running surface. This episode presents how Ansys Fluent models the free surface to examine that patch directly: the pressure on the hull, the spray it throws and the dry transom. It also shows how resistance varies with running trim, and what that means for how the boat is set up.
