I'm taking my 1977 Chris Craft Corinthian out of the water and putting it in my yard to facilitate a remodel. I will be removing both engines and all galvanized-steel tanks to be replaced with plastic. And replacing both engines. Plus a complete update of the interior, plumbing and wiring. Looking for help as to the correct placement and use of cribbing so as to not damage the hull. Also how to move the cribbing for the anti-fouling paint to be applied.
