When launching my 1974 22' oday I noticed that the keel dropped about one half of an inch -- is this normal - I had just replaced the bulkheads and the post under the mast and then had to add a little more to make up for the drop after it was in the water - there is alot of weight on the keel when it is on the trailer and I can see how this could flex the hull - around the keel- has anyone had any trouble with this damaging the boat?
