I would like to deck my 14ft vhull. Is there any product out there that I can use besides plywood. I fish alot of places that only allow electric motors and weight is an issue. Plywood and 2x4's add up the lbs.

Go to www.tinboats.net and do a little searching. Great site if you plan to modify your boat. I used plywood in mine and it still gets around fine on the electric only lakes.

You can go lighter with thinner ply so long as your boat has ribs in the bottom. Then you add some 2x2s on the outside edges to make it solid. Coat with water seal, carpet and screw it down into the ribs.

 

I've also seen where guys found old road signs from a scrap yard and used those across the ribs with expanding foam underneath. You just have to find a way to keep a channel open for water to flow under the foam. This is probably the lightest option if you can find the signs.
