Now that you tell me that the boat is built in two halves I am even more concerned. While they should be able to do a proper layup in the keel cavity, I think that the centerline joint is not so wonderful since it is much harder to get a proper structure with secondary bonds.

The delamination that I am refering to is between the microballoon/epoxy matrix and the laid up keel cavity skin. While the manufacturer could sand and prep the interior of the molding to increase the bond between the matrix and the skin, that would not be easy to accomplish. Essentially you have a poured in place matrix trying to form a secondary bond with the interior of the keel cavity. That is anything but a monolithic structure.
