Non-planing vessel with single hull (2). A foil (10) is fitted below the waterline at the place where the greatest flow constriction exists, in other words at the transition from the relatively broad part (9) to the narrowing part. This foil is situated at a distance from the hull (2) and preferably extends horizontally over as large a part of the hull as possible at a constant distance from the latter. The foil is designed in such a way that, apart from a lifting force, a forward propelling force is exerted. The performance of the vessel can be improved by fitting such a foil. |
