Dwyer has the part you need. The gooseneck mount attaches to the mast with rivets. You will also need a quarter inch quick pin. When I stow the sails I release the quick pin and lower the sail as I roll it around the boom. This keeps the sail in better shape with fewer wrinkles. I will add a flat tang and pendant line at the outer end of the boom to attach at the backstay. That will hold the boom end up while rolling the sail. I also did away with sail slugs and went back to using the bolt rope. No more problems with the mast gate. The sail comes out of the groove when I reef in one large pleat. My jiffy reef lines go thru the reef cringle and is led thru a fender washer on the back side. That way the sail is not bunched under the doubled reef line on top of the boom. After the reef is complete I come about and tidy up the pleated sail.
