I mounted a strip of wood on back wall of laz & another on front, cockpit side. I put hooks on the back wall board. On each side, I have lines run between the boards. Lot's of room to hang pfd's, fenders, extra lines.
A couple of years ago, I decided to add a second cleat & also replace the original plastic cleat on the stern port gunwale . Emptied the laz, removed the drain hoses and crawled down there. I'm 6'3" & it's surprisingly easy to get in. Getting back out was nearly impossible. My son threatened to leave me there & keep the boat for himself.
