[Destroyer]

Gotta agree with Nipper. It looks like a nice deal...especially since he said make offer... that means he's willing to negotiate somewhat. I'd look very carefully at the underside of the boat... check the keel and the front bow especially for large dents or cracks... sure signs that it's hit something hard. Take it for a test run. (Offer to pay for the gas). While on land check the bilge area...make sure it's dry, then, while in the water and before you start playing with the boat at speed and taking water and spray over the sides, check the bilge area again for water. If its wet then there could be a leak or crack. Tap the transom all over, inside and out, with the back of your favorite hard plastic handled screwdriver. You don't want to hear a hollow sound. That means possible rotted wood. You cannot plumb a porta potty... you can buy a head and plumb that. But then you get involved with a macerator, piping, holding tank, etc etc. That's going to be a lot of cutting, fitting, glassing et all...It's easier to empty a porta potty.
