Hello, I have a project that I would like some input/suggestions. I have a boat that the deck doesn't drain properly(the new motor is lighter). The deck is solid, so I was thinking of possibly laying pvc foam over the current deck and taperring it so it drains and cover with 3 layers of fiberglass? Do you think 3 layers of 8.5oz cloth(I'm in the US, so aprox. 290g cloth) will be good...too thin...or overkill? It is a center console, so I would have marine plywood laminated under the helm seats to mount/support. All suggestions welcomed.

Thanks for the reply chris,

The rear deck section is aprox. 8ft x 7ft (2.4m x 2.1m), Normal foot traffic, coolers etc. 
I just wasn't sure how thick the needed to be over pvc foam as I never used it before, didn't know how much flex would it have. My estimate was based on over laying plywood. 3mm isn't too bad, needing that thickness I might use some 1708 or roving I have instead and make it slightly thicker. I don't like using CSM, too messy.
