Looking for some help. I'm currently looking at 1985 Islander 30 Mk II. The boat appears to be in pretty good shape. I know Islanders have a reputation for problems with their compression post sinking or moving. On this boat the post appears fine, but the doorframe to the head, which is hinged to the bulkhead next to the post, is out of alignment and the door will not close. The broker stated this is simply because the boat is sitting in its cradle and not afloat. That made sense, but I'm concerned this could be a symptom of a compression post problem. I'm looking for any insight or something I can check prior to moving on to a professional survey.
