Agreed, $2K to haul the boat and repair the crack would be expected. The problem I have is that I am already paying $2500 for a bottom job, and the crack was discovered in the course of doing the bottom job. The yard wants an ADDITIONAL $2K just to fix the crack. If it is superficial, I would think that would be a lot of extra dough to grind it, fill it, and fair it. They are already fixing other blemishes in the bottom (blisters and scratches) as part of the price of the bottom job. To me, this just seems like another blemish that needs fixing.
I just scooted over there and inspected it closely and took a ton of pictures. I'll upload them later today. It seems to me that if the keel was flexing and in jeopardy of falling off, there would be other stress cracks around the perimeter of the keel/hull joint. There are not. I'm starting to wonder if the crack is simply the failure/delamination of a previous repair job from where the boat possibly hit something at that spot.
