Abstract:
A method for intercepting and yawing an errant sailing vessel is disclosed, wherein the vessel might have been hijacked or malfunctioned and in danger of colliding with an object. The method comprises dispatching a watercraft to approach the sailing vessel and secures itself to one side of the sailing vessel's hull. Preferably, a second watercraft is secured to the other side of the vessel's hull. At least one of the watercrafts is then operated to direct propulsion thrust to yaw the vessel in a desired direction. Preferably still, the first and second watercrafts are each secured respectively to the right and left sides of the vessel's hull proximate to the stem or bow end. The first (right side) watercraft then operates a fluid propulsion which thrust is directed away from the vessel's right side while the second (left side) watercraft's propulsion is on standby. As a result, the vessel is turned rightward or clockwise. Conversely, the first watercraft may be put on standby while the second watercraft's propulsion is operated such that the thrust is directed away from the vessel's left side, thereby causing the vessel to turn leftward or anti-clockwise.
