Keel bolt replacement

[Qben]

Has anyone heard of T30 keel bolts needing to be replaced? If so, how would one go about this since they are cast in the ballast?

Thanks,

Ok, so after some extensive searching, I've found the keel bolt repair thread. It seems that a sistering application may be the most appropriate avenue. Can anyone tell me which category the T30 falls into? Stub for keel attachment or reinforcing grid in the bilge from the reference below?

Whether sistering is applicable depends on how your hull is reinforced to take the strain of the bolts. A hull with a stub for the keel to attach to is likely to have ample strong locations for additional bolts, whereas a boat constructed with a reinforcing grid in the bilge may provide fewer strong positions. If your bilge exhibits space for more bolts—perhaps enhanced with some additional reinforcement—their installation is relatively straightforward.

Thanks,

Hi,
I had the same question about my Tartan 27...how can I check, and some more information on the sistering application?
Thanks,

Typically, to replace the keel bolts, when they are cast, it takes a special pipe bit to over bore the bolts. Then you have to reset and pour new lead to seat them. The same procedure would have to be done for sistering the bolts as most keel bolts have the bottom couple of inches bent at 90* to keep them from pulling out. The keel would have to be dropped, similar to the method shown in my "keel" thread. Keel saga, for those contemplating this procedure for your boat...
