hunter 27 compression post

[dakno]

I have a 1981 h27 that has approxmately a 5/16" downward deflection on cabin sole under compression post. The solid post appears to be sound. There is no noticeable deflection at cabin top. I will be pulling boat out of water next 3 months. I am thinking that I should drop mast, change steaming and anchor lights to led's, and while mast is down lift cabin top and see what is happining at the sole. This boat has a very shallow bilge and where comp post rest is maybe 5" from underside of hull. Question? Does anyone out there know what is under post, steel, wood, fiberglass...? I know most of you will say dont worry about it or throw it away...not an option, this boat has been in my family since 1983 and is otherwise in better than new condition. It would be very helpful if anyone has knowledge of the build under post. thanks
