i'm not doing this project, just thinking of how could be approached best. theoretically.
putting a composite floor in a kit boat with the top already on. approx cockpit size of, lets say 9x16 or so, and trying to keep the whole operation light.
i am thinking of thick nida core, and a bare minimum of bulkheads or beams. i guess it would have to be in at least a couple panels to get it in, butting on a beam or bulkhead. then uprights from the stringers to take out any bounce.
how would you guys tackle this in a way that keeps it light and open underneath?
are any bulkheads needed under the floor to stiffen the hull, or is it stiff enough?

This is how my cockpit deck is built. I installed aluminuim tubing supports from stringers to stiffening joists running under deck.

If you look at Stews pics on his websight, there are pics of his deck installs that may be a big help to you....SW Boatworks
