One additional idea that might extend the life of floor restoration... A good friend who managed a major refit of a 70' sloop used clear LP instead of varnish (in this case, Sterling, which flows very well. I'm guessing clear Awlgrip would work as well). He did 2 coats. Then, in areas where traction was needed, he found soem clear nonskid additive for a topcoat.
It looked incredible and has held up better than varnish. They actually rolled and tipped it (vs. spraying - hard to ventilate) since the floor was mostly a flat surface.
Just another idea...
