Thanks for the welcome, St.Nick.
Sailormon, great post, thanks! Very informative. When checking the bottom, is it only blistering and peeling I'm looking for, or any roughness at all? I've owned a power boat before ('89 Larson Runabout) and recall the bottom being pretty smooth, though a bit worn.
And, since I'm still trying to get a ball park idea, what should I expect if I have a pro strip and apply antifouling paint to a 22 footer?
