For prismatic planing vessels, attitude parameters of deadrise, heel, and trim angle affect hydrodynamic maneuver forces on the hull as shown in experimental data. These effects can be exploited to achieve maneuvering objectives. Demonstrated through numerical model-based simulations, asymmetrical mass distribution on low deadrise hulls affects heel and induces yaw moments that turn the vessel without the use of traditional aft steering mechanisms. On high deadrise hulls, maneuvering by use of a combined rudder and asymmetrical mass results in ~10% drag savings and improved stability in comparison with rudder alone.
