Re subscribed.. Jasoncoopercola, The liner on the 1983 also adds a lot of structural support. The hull is flemsy without the cap. Glassing a rolled gunnel will help with some of the structural issues but I suspect you would need to install some ribs to keep the hull sides from flopping in the waves and causing stress cracks where the bulkheads meet the hull sides. The older hulls, like KrackerJack's have a liner but it is glued in place tight to the outer skin I think. that adds strength. Then his gunnel cap and vertical braces (ribs) are going to tighten her up even further. I have Reels old 74 here that is like Kracker's. That is the best I can determine without ripping into her.
Kracker, your work is just fine, don't beat yourself up. Two layers of 1708?

You are building her heavy.
