I guess I did not explain my self very well.
The floor will be attached on all 4 sides.
The hull side will be bonded to the cleat with epoxy and then will be fiberglassed taped to the hull and floor.
The front will be bonded to the cleat and taped to the floor.
The center part will be bonded and taped to the riser and the right side of the floor (port side) and left side (starboard)of the floor will be bonded and taped together by the wider floor brace.
The back part rest on a bulkhead and will get the same treatment.
Whew I hope that is clear. One thing my wife says is that I over engineer everything. So attaching the floor is a big concern
