I noticed today,while looking at the boat,and dreaming of going for a nice sail out of Salem sound,that there was rust streaking down from the rear of the keel. Is that(does anyone know) from a support of the lead,and should it be seperately addressed in the spring?
Thanks and Merry Xmas

Hey Dana,
Back when I had my C&C 25 (a great boat), I had something similar happen with its keel. There were some unusual raised areas, like bubbles or blisters, on the surface of the keel. One spring I decided to try and smooth them out, as part of an overall bottom cleanup. When I started sanding the bubbles down, they opened up to reveal pockets of rust. Once I cleaned these pockets out and filled them with epoxy, there were no further problems.
The pockets of rust were apparently the result of impurities in the keel casting, where bits of steel or cast iron had become included in the lead used to mold the keel. Where these impurities were close enough to the surface to be reached by moisture, they would corrode and expand, causing the blisters. In theory, Capricious' keel should be lead with some antimony added for strength and your keel bolts should be marine grade stainless steel. Since I have never heard anyone accuse C&C of stinting on the keel bolts, I would assume that you may also have encountered some impurities in your keel casting. Can you access the area showing corrosion in order to open it up? Based on my experience, this is likely to be something minor so don't get upset until you have a real reason.
Have a wonderful Christmas!Marcus from Carriden
