Re: Bolt on Keel

I do not think it is valid to include radical, state of the art race boats in this discussion. They are built to minimal safety factors and as a result they can break in many areas.

I have about 6,000 boats on the water and many have bolt on keels. I am not aware of any keels having fallen off for any reason. And, believe me when I say I am among the first to hear about failures like that on my boats. I remain convinced that for me the bolt on keel is the best way to go. It gives the designer freedom to design the most effective shape without having to allow for "positive draft" for mold release.It reduces frontal area due to lack of a "skin". It insures that the keel will be either one pice lead or cast iron whereas the internal ballast can be anything from cement to steel boiler punchings.
