this boat needs to be done in the spring. so I plan on getting this done in 2-3 months. I'm actually looking into 30 gallons total. The stringers will be bedded with PL. I looked up on how much resin gets sucked up into the csm and 1708 not even considering PB, I should be right there with 30gallons to finish this 19.5ft boat with. 2 tabs for the stringers and capping with csm. 1 layer csm on the bottom of the deck and 2 layers csm + 6oz woven for the deck with 1 layer 1708 for the tabbing. It all adds up I guess.
