Something I've been doing while the boat is out of the water is replacing anything below the waterline that is broken or might break. Some things that often get overlooked are the hoses that run from the cockpit drains to the thru hulls below the waterline. Before we bought her, I noticed that the drain hoses on Winbrandt were old and dry rotted. Everyday that she sat in the water I worried that one might give up and I would find my boat on the bottom of the Pamlico. A few new hoses and an hour or two of labor is cheap insurance. And there's no dollar sign on peace of mind.
