“Brian, I just removed the two pieces that were bolted to the top of our bunks for a stepped hull, these were for a 289. Oh! Just saw you are in Grand Cayman 🙂 I was going to offer them to you. Anyway they look to be 2 1/8″” in height, 8′ in total length, with the last 12″” tapered down to 1″” height.”
