If we were ordering a new 25 or C-Cat today we would have it shipped with a portapotti. Much less hassel than a built in head-no smelly hoses, no smelly tank vents, no expensive rebuild kits and you save the space of the holding tank.

Keep in mind that, on a boat, sooner or later, everything will eventually break. Then ask yourself whether you are prepared to deal with it when it does break.
