After viewing the archives for entries about compression post problems I'd like to expose the one on my boat for examination. However, in the articles I read I didn't see where anyone had disassembled the surrounding box or actually replaced the post while the mast was still in place.In some of the archived cases, the surrounding box was all that remained of the support system. I'm wondering if my post turns out to be rotted and I remove the surrounding box, what's the likelihood that the mast might come crashing through the cabin top.I believe relieving the tension on the shrouds would be practical, so they won't be pulling the mast downward and I'd only be dealing with the dead weight of the mast.Any thoughts on this before I start taking stuff apart?
