It depends on how far apart your supports are. We just bought an Alumaweld, and 1/4 would make me feel safe from dents and such. But the price made me curl up in a ball and cry. :shocked:
So we are gonna stick the thin stuff over the top of plywood. I know there is still wood under there, but for a grand difference, I can live with a little wood.
The weight difference is minimal( hey the boat weighs probably 3K or so. What difference is a hundred fifty pounds spread out over the whole floor space? In my world that is about one dog.
Have fun with the sunglasses til it gets dulled up a bit.
Mark and the dog.
