The deck will be screwed to the stringers and bulkheads,there will also be a layer of thickened resin on top of the stringers/bulkheads to allow for any undulations. The stringers will be screwed at the overlap permanently,when i glued the two layers of stringer together i put resin between the two and screwed and clamped them until the resin had set then removed the screws.
Glass tape saves cutting as you mentioned and is used for tabbing in.
Your stringers are taller because you have a later boat that has a self bailing deck ,the deck was raised to be above the water line and they increased the cap height to allow for the loss in freeboard.

Going to keep bugging you!
1. Why not poly...which one sticks better to the old glass too?
2. I'm trying to get a grasp on how many yards of 50" 1708. How much did you buy/use...or did I miss that somewhere?
We found one vendor selling a roll of 48" yard very reasonably but that seems like a lot if only doing one layer on the stringers and two on the deck. We'll take some measurements this weekend on the boat to come up with our theory of quantity.
3. How much resin would you also recommend based on my photo and if we had todo two tall stringers front to back. My buddy thinks 3 would due but I'm always the pessimist and think 5 is the safe thing.
