Barry's Right
Barry is right. Before I put the guide onto my trailer, it often took us several tries to get the keel in the molded "V" on the trailer. The keel sometimes did have the lean that you described in your question. With a guide on the trailer, we can put the keel into the "V", first time, every time. I never left my boat on the trailer without the keel in the molded "V". I felt that this would put some stress on the hull. The purpose of the "V" is to take the weight of the keel off of the hull while the boat is being trailered. I don't think that the lean would be apparent when the keel is lowered. There is a taper on the upper rounded part that goes into the trunk, that will take up the clearance that allows it to lean. In my opinion the trunk is very strong. So is the keel.I would be a little concerned about someone not puting the boat back onto the trailer correctly. Was it the previous owner, or was it a yard? I think that you should have the boat checked out very carefully. Aldo
