Abstract
PURPOSE: To lessen the radius of turning in direction of a craft as well as to stabilize turning performance of the same by providing a moving bow at the force part of the hull and steering it interlocked with a tail rudder.
CONSTITUTION: The moving bow 2, which is directed forward at the time of straight sailing, is turned toward the craft's proceeding direction at the same time as the tail rudder is steered, when the resistance force of the water give the hull 1 a moment of turning in direction both at the bow and the stern. The craft can thus turn by small radius with stability. The moving bow 2 is coupled with the hull 1 by a coupling device 4, which is supported by a shaft 3, and operated by a steering machine with a gearing etc. as a means.
