Ballast Material in the Daggerboard

Post by Southern Gales » Sun Oct 12, 2014 8:53 am

Anyone know what was used in the daggerboards for ballast? I'm hoping lead and not some type of corrosive metal that will expand if there is water intrusion.

There's a slab of lead molded into the lower portion of the board. The rest is foam, wrapped in glass. The glass skins were made in halves so there is a seam along the leading, trailing edge, and bottom. (Just like the rudder). Sometimes these seams can open up, making the board hard to raise. There is a lot of discussion on this including a picture somewhere.

I have an S2 6.9. I appreciate 7.9 class allowing me to share your forum. I hit a Shoal with the keel. I could see the front of the Keel was damaged. I was not able to see further up the Keel in the back. Now that I have the Keel out, the entire back side of the Keel has split along the mold lines. Has anybody had experience with this sort of thing happening without hitting a Shoal. I'm having a hard time figuring out if that split at the back is related to the Shoal hit on the front. Any thoughts?
