I have read that article and have really just been debating how i should do it based on what you have there as a guide, and i think i will do two layers of 1708 on the stringers doing 6" and 4" layer from the hull on to the wood, but not go over the top, definitely going to do PB fillets.
Is 1708 really more structurally "sound" than 1708 or is it really just based on the amount of waterproofing properties it has?
Do you guy think it would be a good idea to make the stringers as an I-beam design out of the 3/4" plywood i am going to use or stick with the straight design and then add cleats to screw the deck down?
