So I got my new carb in the mail. And found out I have to replace a deck. If it is not one thing its something else with boats. So I am going to replace my floor.<br /><br /> Ripped the old carpet up and found that I have fiber glass and mulch for a floor, wierd thing is the stringers are solid and the foam is dry. But I will take some core samples to be on the safe side, after I get the rest of my floor out.<br /><br />So when I get ready to install a new deck would it be wise to use 2 1/4 inch sheets of ply wood with glass in between the sheets then on both sides? Or just get some 1/2 inch and glass top and bottom? I am looking for a sturdy floor and light wheight.
