He said: ‘A 17-knot boat is highly likely to be a planing boat that skims across the water.’ The BMT director said faster craft which planed along the surface of the water created less wake than slower boats which displaced a larger volume. Once the vessel started planing with a lower freeboard aft the fender would be low enough to bounce on the sea surface.
