A man over board rescue system 100 may comprise a main body 200 with the main body quickly and easily being attached and detached to a ship's bitt. Thus, the system may be quickly set up prior to departing and quickly put away at the end of a voyage. The system allows for the fast and efficient rescue of a person overboard without need for a rescuer to enter the water or to risk bodily injury in retrieving a person in the water. The system provides secure mechanical means allowing for a winch to be used in the support of a person which is a significant departure from the prior art.

An arrangement of fenders nested together for compact storage, the fenders including two or more cylindrical bodies having a cavity accessed through the fender top, the fenders being similar shape but graduated in size such that the cavity of a larger fender tensionally receives the next smaller sized fender, the outer diameter of the smaller fender equal to the inner diameter of the larger fender cavity. A fender has a rigid inner core surrounded by a compressible shell made of foam or similar material. The inner core has attachment points for a rope or line. The smallest nesting fender in the set has a cavity diameter sized to fit a commercially-available, off-the-shelf fender. The fenders may be separated and deployed at individual locations on a vessel, or kept together and deployed as a single fender capable of absorbing a greater impact than any of the fenders individually would absorb.

A central floating device with a plurality of peripheral connection points and tethers. The tethers may be retractable, and are of sufficient length to allow the users some amount of spacing distance from each other. Each individual user thus maintains a separation from each other so as not to interfere with each other in the pool, lake, or body of water while remaining tethered together. The floating device may further include cup-holders, lights, storage compartments, and an anchor.
