I think one to three degrees of keel being crooked front/back might not be noticed out of the water, and would make a difference in pointing. And that the keel being off center both vertically and front/back is very possible. This is not unique to Catalina. The solution with racing boats is to 'template' the keel. Which refers to buying a fully dimensioned template model of the designed keel (usually minus some weight) and having the yard precisely grind it to that shape, and of course the right angles.
