:Checking the keelbolts" is more than looking in the bilge
where you can see the ends. Checking the keelbolts means removing or exposing them to see if there has been water
incursion along their length, and (therefore) any corrosion
or other damage.. This is important because corroded or damaged bolts can lead to the keel falling off. (see " Drum".) Depending upon how the bolts were installed, this can mean having to entirely remove the keel by taking off all the nuts and hoisting the boat, hoping the keel comes away from the hull without too much additional convincing. If problems are evident, it is a good thing to have done: they will need fixing. If no problems are apparent, you just spent a lot of money
for nothing, and will have to spend a good bit more to have everything put back together, hoping the job your workers do is at least as good as what was there before.
Most people examine the keel-hull joint for signs of "issues" (why it would be good to get a wider-angle photo
of the longer joint, as suggested) and check to make sure the nuts in the bilge
are good and tight. If there has been a grounding it also makes sense to check the top trailing edge of the keel where it meets the hull, to see if there's been compression
cracking (or repairs!) there. Nice clean threads on the bolt tops are better than rusty ones, too, along with broad washers or backing plates
to spread the loads. It these areas seem "ok", most people leave it at that. Keels are generally attached with hefty safety
margins. You don't actually hear about that many falling off, and so unless there are real suspicions of trouble, inspecting the keelbolts is something you leave for the next owner to take care of.
