I am not totaly sure, but if Iam not mistaken pressure treated is really corrosive if its in contact with aluminum or steel.

well, this helps, the difference appears to be in quality of wood used and gaps in wood etc.... so if I was to re-floor my boat, I could use regular pressure treated and perhaps apply a lacker to further seal it. .... and save myself a lot of $$$.

I'd just use regular exterior grade ply, personally leary of toxins in pressure treated wood. I built a 16' boat out of regular ply, just painted and it has stood up great to a lot of (ab)use.

If you only want to do the job once...spring for the extra bucks and use marine ply....Been there, done that....

This is pretty important.
Your boat must be fiberglass then?
If not the copper in the pressure treated wood will be a problem.
