发明名称 Watercraft
摘要 The present invention provides a watercraft having steering components (steering tabs or stabilizers) for maintaining steering capability even while amount of water ejected from a propulsion pump is decreased. The steering components are movably disposed on a hull of the watercraft at or below the water level on both right and left sides to be in an "Operating State" in which resistance of water is larger or to be in a "Non-operating State" in which the resistance of water is smaller in accordance with steering operation. Furthermore, a mechanism for absorbing an external force acting on the steering components in the "Operating State" is located in a system for operating the steering components. The mechanism reacts to the external force to allow the steering components to be transformed into the "Non-operating State."
