I had a bare nonskid floor. No teak. Had a rotten balsa core so I cut it up and put it out with the trash. Building a new one with nice easy access to the second bilge. Planning to use closed cell foam for the stringers. CoreCell. Wood probably end up just like the verm, black, rotten and smelly.

I think you could save a floor. There's no core around the edges. Cut where the floor meets the liner and tab it back in when your done. It'll be heavy especially with the teak and holly.
