发明名称 Method of steering a craft
摘要 A method of towing a craft having a fore rudder and rear rudder using a towing vehicle with the fore rudder and rear rudder initially oriented parallel to the length of the craft such that the craft follows directly behind the towing vehicle. The fore rudder is rotated to a position less than 90 degrees off parallel to the length of the craft. The rear rudder is rotated in an opposite direction to the fore rudder and to a position less than 90 degrees off parallel to the length of the craft, causing the craft to move off to the side of the track of the towing vehicle while the craft maintains movement substantially parallel to the towing vehicle, producing an of offset tow.
