Just a progress note on my Joel White Pooduck Skiff: I lined the mast partner hole with leather, secured with tacks and Pumbler's Goop. Note the brass half-oval rub strips positioned to protect the seat edge from abrasion from the halyards.
I installed the trunk cap using silicon bronze screws and 3M 5200 adhesive. The cap has a couple cleats on it: one for the the jib sheet and one for the centerboard pennant. The plans called for wooden jam cleats but I've gotten too lazy this far into the game to carve them myself, so I just bought a couple small brass ones. I put a little monkey's fist on the end of the pennant to give it more of a nautical flare.
I also installed two larger cleats on the sides of the centerboard trunk for the jib and mainsail halyards.
The gudgeons were installed on the transom, with screws and more 3M 5200 (I like that stuff!)
