I'm with Glenn.

The only cases of keels falling off that I know of we
- Ultra go-fast boats where the designer was trying to save the last gram and
left .01% safety margin
- Old boats whose maintenance (including keel bolt inspection) had been sorely
neglected.
- cases where the wrong bolt material had been used.

Use the right bolt material and a non-permanent sealant and pull a bolt every few
years to see how they're faring.

I have no experience dropping a keel other than as sidewalk supervisor
removing a fin from a Hunter. One thing I did learn was not to use 5200.
The boat was on well braced stands with a fork lift holding the keel.
Everyone thought that once the nuts were removed from the bolts it would be
a simple matter to just lower the forklift. Not So! The 5200 held the keel
firmly. After much nerve wracking wiggling they finally had to saw through
the 5200 and then spend the better part of a day scraping the joint
surfaces.

Hi,

Might be handy for an offshore boat, as it's not unknown for keel bolt
studs to snap at the nuts.

cheers,
Pete.
