Abstract

Abstract An accessory for attachment to a power boat for providing a relatively high, easy release, tow rope attachment point above the general level of the boat stern is disclosed in two embodiments both of which have a ring with a stud adjacent thereto to allow a tow rope bight to pass through the ring and over the stud with the ring preventing inadvertent detachment of the tow rope from the stud. The stud and ring are connected to a sleeve which in one preferred embodiment accepts a pair of at least L-shape members passing therethrough for attaching the ring and stud to the boat.
