O'Day 322 Bridgeport
I have a '77 O'Day 322 that looks like there's rust coming from the starboard and port chainplates. How/what do I open up to inspect them?
Thanks, J. Geils

Definitely, looks like water intrusion to me. Not an O'Day 322 owner, but I suggest that you take a multi-tool to remove a bit of the fiberglass to inspect the U-Bolts. Better to have a patched interior and to be sure of what the issue is. I suspect that the dark brown in the pics is a bit of balsa core deterioration due to water intrusion. The only way to be sure is to do a visual inspection of the chainplate system.

Can you share some pics of where the U-Bolts penetrate the deck?

That looks like water is getting under the bulkhead tabbing. I am not an O'Day owner. I do not see chainplates in the images.

Sorry to say, but you don’t have an O’Day 322…they didn’t make them until 1986 or 1987.

On the 322, the chain plates are rods that are visible…

I don’t know how to remove the wood cover on your chain plates. I see some plugs on the end, so if nothing else, you could drill them out and remove the screws holding the front piece of wood and see if that gets you access (but I think you will need to remove them completely to get full access.

Good catch Greg. Perhaps an O-Day 32? The interior pics of it shows a similar bulkhead arrangement.

Thanks, all!! Yes, not a 322 but a 32' with center cockpit (I assumed that 322 meant 32' center cockpit with 2 cabins). There is definitely water coming from the foredeck whose core is soaked. I thought that the brown was from that but the surveyor put potential rust in the report, so like you say I better check it out. I will include exterior pics next week (hosting family for Easter), and again, thanks for the support.

Get some photos of the deck where the chain plates come through…that may be helpful. But you are going to have to figure out how to get the wood trim off the chain plates in the cabin.
