Is lateral movement of a bolt-on keel that causes flex at the stub normal on any sailboat? The boat is a fresh water 1984 Pearson 25 (aka US 25 and Buccaneer 250) with a lead fin keel that I can get to move about ˝ in. port and starboard as measured at the bottom of the keel. There are minor gel coat stress cracks at the shoulder of the stub where it meets the hull. The seam between the keel and the stub is tight, perhaps too tight as the keel boats are pressing into the cabin sole. I will drop the keel three inches to make an inspection, but if it is not obvious that a bolt or two are loose in the lead will it be advisable to “sister” the bolts and/or reinforce with fiberglass the portion of the bilge that sits over the stub. Any serious advice is welcome. Many thanks.
