My project inches along and for any of you who were following, my apology for the weak performance of keeping up this page. It is a hobby, after all!
The floatation foam is in, I've installed the ply flooring and designed an aft bulkhead to allow installation of a live well/fishbox in the transom. Photos to follow.
I installed four backing plates made of 2 layers of 1/2 inch ply plus 18oz glass in the footprint of what will be the T-top. Since there will be no way to access the under surface of the deck later, the T-top will be fastened with SS bolts/nuts embedded into these footings (see Gougeon Brothers, 5th ed. p 136)
Deck is 9mm ply, will be covered with 18 oz glass, then teak.
