I'm fairly new to boat ownership and have joined a co-op (10 owners) who are looking at buying a 1987 CS30
Harbour Yacht Sales Ltd.
I've looked at as much as I can online. We had a rigger look at the rig today, and he noticed some pock-marking on the keel (it was on the hard) and thought it was a cast-iron (steel) keel with some corrosion.
From everything I've read, CS used a lead keel. Has anyone heard of such corrosion? The prop and shaft also display similar pockmarked corrosion and the surveyor has mentioned it needs to be replaced. We are just trying to figure out if there is some galvanic soup happening somehow. Keelbolts have some surface rust, but nothing concerning in the surveyor's eyes.
Anyone seen anything like this before?
