Although I did add some cockpit inspection ports to my '69 Sunfish, I didn't want to add any on the deck. Instead I cut access on the hull bottom and epoxied with West Systems...some 1/4" aluminum plates to the underside of the deck. Then I was able to screw and tap the hardware on, never having to worry about the old wood blocks failing again. Plus the aluminum was able to spread out the "load" better. Then, just glassed up the bottom. Anyone do this and was I crazy? I thought it was a great idea actually. The pictures don't show...but I finished off fairing the glass work and then gelcoat. SInce I beach the boat often and scratch the bottom, I wasn't too concerned about the bottomsides that much either, even though the final glassing came out great.
