Joe, My boat is a 79.
I am sure its probably a combination of all three- that cause the actual crack. The small surface area of support from the factory probably doesn't help things.

Derek, what year is your boat? I just had my ’81 #4795 pulled and no smile, I wonder if it is a function of age or can be caused by running aground or improper blocking.

[2 Attachments] [Attachment(s) from Derek Atkin included below] This is by no means gospel. just my thought. Attached is a shot of the front-most keel boat washer. As you can see its now conical in shape. If you take the movement of the bolt due to washer deformation and the collapse of the surface underneath - you can certainly see why a tolerance grows and thus allows the keel to drop a little and generate a crack. I have also attached a shot of my remedy. 3/4" aluminum blocks that are acting to spread the load of the keel on the keel floor. If you look around the bole - you can see the larger flat washer - which is about the same size as the washer on the original fitting. I had plates made for every keel bolt, significantly increasing the surface area that spreads the load for each keel bolt. They are fitted with stainless lock-nuts and washers and were set in epoxy to take up any surface irregularities. Hopefully this increased support will prevent and further separation between the boat and the keel.
