Sub Floor (S25)
I whole heartedly second the suggestion to replace the sub-floor in pieces (I managed to get mine in with 2... but 3 probably would have been easier!). I tabbed every 4-6" wherever the plexi was exposed with round head #8s (I'm assuming this helps with structural integrity, cause I'm not adding any fiberglass!). Another advantage is you can take it all apart later if necessary (I only replaced half the rotted stringers below... couldn't wait any longer to get out there!). I was hoping to leave the others, but (thanks to another post) now know where that "mossy" smell comes from!I discovered cement (!) b/n the first two stringers forward of the mast, I'm thinking of levelling it out and putting ceramic tile on top - anyone tried that?!Finally, if you can't find marine ply here's an alternative: look for "Crazon" - it has a paper backing on one side and is the stuff they make road signs out of (i.e. 3/4" ply VERY resistant to the elements!).
