I am thinking of installing a Nicro, Vent o Mate, or equivalent vent of sorts on my 260 for when it is closed up and sitting at the dock. It currently has nothing and feels/smells like a jungle now that summer is here. Any recommendations of where to drill 4" holes in my boat? Pics please. I really want to stay away from installing one in the front hatch since I stand on it when hoisting the anchor.
