Thanks for your progress report, and the great pictures. On my lake, there's a seasonal drawdown, and too many oversized powerboat wakes. The late-summer drawdown means lifting the Sunfish nearly three feet off the water to pull it onto the dock. So as not to renew a back injury, my solution was a long lever, which put the bow handle "in-tension". (And not "in-shear"). While screws had worked for decades, the old original bow handle eventually broke. A new one is bolted now, but wish I'd thought to "pop the deck" instead of cutting into the side. (That became a very tight space in which to bolt the bow handle). "Arthrosopic Surgery" on Sunfish | SailingForums.com This picture below shows the interim "kayak" bow handle, temporary plumber's strap "fix"—and two different inspection port lids. One shows a container for O-ring seal grease, and the other is a bayonet mount with an old CD pop-riveted to it—for use as a signaling mirror. On my borrowed Sunfish, I moved the coaming slightly, remounted it, using S/S screws. (No sealant, as with "the boys" around, it was likely to be knocked off again). Even a trace of silicone resists adhesives, resin, and new paint. I'd use a sealer without silicone—something else—or nothing at all. .
