Each propeller of the twin-screw ship develops a full-speed thrust of F = 325 kN. In maneuvering the ship, one propeller is turning full speed ahead and the other full speed in reverse. What thrust P must each tug exert on the ship to counteract the effect of the ship's propellers? Assume a 46 m, b= 120 m, c = 16 m.
