Picked up a mint condition '73 sunfish in July. I sailed the boat all summer knowing it was was heavy and needed to air out the hull this winter. I am going to cut a hole in the front of the cockpit for an inspection port. My question is, would it be a bad idea to let it air out over the winter outside? The boat will be flipped upside down on a rack outside in New Jersey. Would this be a bad way of airing it out?
