Identification of maneuvering models for wind-assisted ships with large rudders using virtual captive tests

International Journal of Naval Architecture and Ocean Engineering
Ships with wind-assisted propulsion systems (WAPS) are often equipped with large rudders to compensate for WAPS-induced drifting forces. The WAPS also significantly affects the effectiveness of mathematical models used to describe the ship’s maneuvering ...
