“ Incoming water flow exerts a force on the tug. The point of application of this force is the lateral centre of pressure. The direction and magnitude of the force depends on the underwater lateral plane and shape, the angle of attack, the under keel clearance and on the speed squared. Speed, therefore, is a dominant factor.
The exact location of the lateral centre of pressure and the magnitude and direction of the resultant force created by the incoming water flow for different angles of attack and speeds can best be determined in a towing tank. ”
