While replacing my lifelines last week, I noticed for the first time that the bracing arm on the starboard aft gate stanchion was significantly bent. I went through the photos from the pre-purchase survey and found, as I suspected, that it had been damaged before we bought the boat.
When I removed the stanchion (in order to re-bed it) the arm sprang out of alignment about one inch at the base. I was able to muscle it back so that the screw hole aligned with the threaded hole in the hull. I put a double layer of Bed-It tape on that joint in an attempt to compensate for any remaining misalignment.
I'm now considering replacing that gate stanchion and I'll probably have to replace the base plate that is through-bolted to the gunwale. I believe that I'll need to drop a portion of the headliner in the aft cabin on the starboard side in order to get access to the nuts on the underside. It's not obvious how one would go about doing that. Any tips or hints?
