I don’t know anything about this outfit, but saw an add while skimming through a Ship Shape TV episode. I don’t know if you have caught this cable TV broadcast, but it occasionally has some good information (and sometimes not, but they try). Only thing on TV I’ve seen that tries to address boating maintenance and construction. Mostly fiberglass sportfish stuff, but working on boats is working on boats (if you need your fix) :-)
Anyway, this online vendor back copies on DVD of the series if you have an episode you want to own.
