How to Fill Holes In Your Boat’s Hull | Sailboat Restoration Ep. 20 

That's good to hear. These older boats have so many more thru-hulls than necessary. I closed two more recently. The intake for the galley sink. I am running it from one of the freshwater tanks. The sink drain will feed to the gray water tank off of the head. Two holes eliminated with these changes.

@@Even_Keeled You're doing a gray water tank in a boat that size? I'm surprised you have room. Or do you mean the black tank? My boat has even more ridiculous thru hulls, like the macerator discharge for the black tank, which is below the waterline. It's so hard to tell when it's done pumping, and is just an unnecessary leak risk in my opinion
