Pulled chainplates on hull #124 today. Photos are from the starboard lower aft chainplate (the one in the pilot berth). Seems Pearson failed to install all three bolts on my boat. The top position is drilled in chainplate itself, but not the fiberglass. Lower two bolts were bent and stretched. Confident I'm the first person to pull the chainplates since our boat was built in 1977.
We've restored three Pearsons - Triton, P33, and now P365. I've heard rumors about Pearson's hasty production line in the 1970s, but this is my first direct encounter. Failure was imminent.
Survey wouldn't readily catch this defect, as they are normally concealed. Check your boat carefully!
