Re: Replacing lead Keel bolts


The generally recommend design spec for keeps is that each bolt should be able to support the entire keel alone, at a minimum of a 5 times safety factor.

If you are really ok with that safety margin you might as well go down to 1/4" bolts. There is no reason to use anything close to the size you are currently planning on, and 1/4 will give you about the same strength as your design.
