ABSTRACT:
A sailboat with a device for retrieving from the water a person who has fallen overboard. The device consists of a crane mounted on strong, cylindrically-shaped metal tubing fitted over the shroud of the mainmast of the sailboat. The metal tubing consists of an upper tube and a lower tube, the upper tube having a smaller diameter than the lower tube and fitting inside, and has bushings at the top and bottom and also at the point where the upper tube is inserted into the lower tube. The crane consists of a crane arm that can be moved angularly outward and is controlled by a line secured to the metal tubing. A block and tackle with a T-bar rescue device extends from the crane arm. The T-bar rescue device is lowered or raised by the use of the block and tackle device and a hoisting rope, which rope can be drawn manually or by the use of a winch attached to the main mast.
