new floor

[usmma2013]

One of the boats I'm looking at will probably need a new floor, how much of a job is it with a V20? I've redone the floor on a runabout before and it wasn't too hard, just cut the old floor out, cleaned up foam and new foam (stringers were fine!) and glassed in new marine ply. It took me two weeks or so during the summer, but I'm pretty sure now that I know what I'm doing I feel like I could button it up in a few days, just didn't know how the Wellcrafts were built. Anyone here done somethin like this?
Thanks in advance!
