Just several layers of styrofoam glued together and fitted to the hull so you get a flat subfloor and then thin plywood glued to that - all one piece.  Weighs nothing compared to a piece of 3/4" plywood.I look at all these other boat mods with a bunch of 2x4 joists supporting plywood and I think "Not for me, the whole point of an aluminum boat is that it is light in weight . . . . and therefore efficient.  So, yeah, I want more deck area, yeah I don't want to trip on those aluminum stringers, yeah I want it to be quiet, so yeah, put a deck in it, but don't add 150 pounds of studs and steel hangers and aluminum angle and pop rivets and plywood and carpet and glue to  a sub 200 pound boat to do it.Another thing, take care about raising the center of gravity.  Compared to glass boats, aluminum boats don't have a lot of mass down low, so that makes them even more tippy when you put a deck on them.  Stock, when you're standing in one, the floor is BELOW the water level line at the hull.  it's a proper pendulum.  Raising the deck too much creates instability - an upside down pendulum.  A couple inches to flatten the floor is OK but 8 or 10 inches just to make it resemble a big heavy dead weight glass boat?  Not good in my view.  Mass above the water line?  Not good.  Yeah, I'm guilty of it, but as little as possible.Jons are better than Vs in this respect but they all lack beam, and yes, put weight below deck and out to the sides; every little bit helps.</blockquote>
