1. A single hole 8mm diameter is drilled in the fore/aft in the bow on the centerline approximately 2 inches above the intersection of the anchor locker floor. The outside of the hole has an aluminum Tylaska ring mounted to provide a friction free wear surface that 6mm Dynema line passes through.
2. A 3/8 inch G10 plate approximately 5 inches x 1.5 inches has been bonded inside the bow where the hole was drilled to provide reinforcement for the bob stay stopper
3. A Dynema loop is formed around the outer end of the bow sprit in front of the U Bolt. The 6mm Dynema is approximately 8 feet long and runs through the hole drilled in the bow.
4. The Dynema is terminated inside the bow by tying it to the center of a 1/2 inch stainless rod 3 inches long. This is set so that when the bow sprit is fully extended, the bolt is tight against the G10 plate bonded inside the bow. A loop is provided at the center of the rod to attach a bungee for retrieval.
5. A bungee cord is run inside the anchor locker to automatically retrieve the Dynema inside the anchor locker when the pole is retracted.
Pictures are attached. Should this modification not be allowed for OD racing, it is easily "disabled" by slipping the Dynema loop off the end of the bow sprit and attaching it to one of the bow chocks.
