I know this is a difficult question to answer, but what would a very rough ballpark in hours required to cut a floor out, grind down, add glass to reinforce thin hull, build a new stringer grid system, and seal it all up? No transom work required. 50 hrs, 100, 150, 200, 200+ Just trying to get a rough idea what I may be looking at to get this done on a an old boat I just inherited. The transom was done professionally 1 year ago. This is an 20' runabout I/O Thanks
