An accessory or an accessory mount for a yacht comprises a device (1) not involved with the normal operation of a winch and having an integral supporting leg (3) which is adapted to locate in the handle receiving socket of a winch. The leg (3) is designed to be a jamm fit in the handle receiving socket, and has a thread (5) at least towards its upper end. A threaded ring (6) engages the threaded upper end of the leg (3) and is screwable down the leg (3) so that it will engage the top of the winch and force the leg (3) out of its jamm fit with the socket.
