I believe our C&C yachts use lead doped with a percent of Antimony. The Antimony adds strength, hardness, oxidation resistance, and aids in the flow for the casting process.It not like pure lead, and the properties are not the same. maybe we have some metallurgists in the group, and they can comment ?

The keel is slowly getting shorter. If I keep the boat another 50 years I won’t be aground at extra-low tide!

Lead is soft and eventually they would pull upwards slightly. I would assume that is why. I have been planning to contact MARSKEEL and get some pro info.
