Michael,
Your main sheet cam cleat looks just like the one I removed from my West Wight Potter 15 when I converted it to aft sheeting.? I just acquired a Starfish which only has a nylon horn cleat for the main sheet in the vertical lip of the cockpit.? I wanted to install the aforementioned cam cleat, so was happy to see you've done this.? I don't think the underside of the deck is readily accessible on mine to easily put on a backup plate.? Is yours?? How did you prepare the hull for that installation?? Any pictures would be appreciated.
