Patent attributes
A system adapted for stopping and launching boats. The system includes a boat, in moving water, with an interaction member extending outward from its hull. The system includes a boat capture and launch assembly that includes: (a) a body; (b) a drive mechanism rotating the body; (c) a capture arm with a first contact surface on the body; and (d) a launch arm with a second contact surface on the body. When the body is rotated into a first position, the capture arm extends outward into the water to catch the interaction member and stop the boat. When the body is rotated through a range of second positions, the interaction member abuts the second contact surface and a launch force is applied to accelerate the boat in the direction of travel of the boat and water.
