So dropped the fuse panes to do some wire chasing and 2 insects came out that may have been worker termites.
So rather that wire chase or install finished pieces, I proceeded to rip out the rest of the rat fur and unscrew all the wood.
Screws were frozen as cement. Busted out the drill with a hammer drill option it worked miracles! It sheared off the tip from 2 #2 phillips bits in the process?!
2 screws refused and I broke the head off one and got the other out with vise grips.
Under the fur was lots of sand so that was the perpetual grit everywhere.
Back deck is in 3 sections 2 that are 2.5 X 8 footers to the front and a smaller one across the stern. Hopefully tomorrow I can yank all of it out in case of termites and toss in a sheet of standard wood as a temp floor.
Depends what I find bug wise.
On the bright side the back pieces should be easy compared to the bow and port side.
