Day 2 lighten up the sleekcraft

[steven engholm]

Interior- tanks- carpet is out. Floor is .750 thick with a lot of resin. It lays right up to the outside stringers. Measures 4x8.like to replace with a light product. Anybody work with coosa board? How about a lightweight ply? I ground down to the wood , seems good and solid.Having trouble with images for some reason.Any response would be helpful.

If the wood is good.... leave it as boat builders... might have an idea...strong floor/bottom.Not all boats are potato chips.....

While plywood is good floor material, it is heavy. The same strength could be achieved by using coosa. A 3/4'' 26# density coosa panel with 1708 on the underside and 1 layer of 1708 covered by a layer of 1.5oz mat on the top would be plenty strong. Wont hold screws so you would have to make a plan for that. Not really a big deal though. 3/4 plywood is 70#'s or so, and with the same glass on it weighs nearly 100#'s. Coosa would come out at about 30#'s less. So it comes down to needing to shed the 30#'s. The cost would be 500 - 600 bucks to use the coosa 1708 and vinyl resin. Slightly more for epoxy resin.
