Alberg 37 Chainplates
Just bought an A37 great condition but chainplates are original and one is showing signs of fatigue. Boat is in MA and I am in Annapolis. Anybody have pictures or dimensional drawings of the chainplates out there - Mark II version. I believe they are all straight bars. Just trying to save a trip or two up there before launch.

Re: Alberg 37 Chainplates
My A35 had 1 1/2 X 1/4 chainplates. I moved the shroud plates outboard and beefed up to 2" because of the leakage which eventually gets into the deck core and down into the bulkheads from the thru-deck configuration. It may be worth a look-see (if you have not already done so) to determine if there is any leak damage to bulkheads or deck core rot. Replacing the bulkhead(s) is a big job.

Re: Alberg 37 Chainplates
I have been told the A35 chainplates are the same as the 37. They do look like 1 1/2 x 1/4 in the pictures so that matches. Do you know the length?

My surveyor did spend a lot of time examining the bulkheads and all is well except for a couple small places in the tabbing which is apparently pretty common on these older boats.

Thanks for your feedback.

Re: Alberg 37 Chainplates
Yes, the tabbing does come away in places. I still have to redo a couple of spots. I don't have an old chainplate here at home to measure. Actually, used them for backing plates with the new chainplates. Next time I'm over at boat will measure one although I'd suspect the length could be different on the 37. Did you check the A37 websites? I think there is still an active owner's site.

I also replaced the masthead and bow plate pieces and the wire/ends. The wire and swages all looked good but it all could well have been 40 years old. The bow plate showed the most significant crevice corrosion of any of the plates, maybe because of the welds. It's a challenging piece to fabricate because of all the bends and the front being beveled into the glass. The masthead fitting can be beefed up a little bit without adding much weight.

Re: Alberg 37 Chainplates
There is an active a37 group and website. There is surprisingly little information on chainplates anywhere though. I definitely want to have a look at the bow plate but it surveyed OK. The tangs and sheaves on the mast head were all OK and are less than 10 years old as is the wire stays/shrouds. Chainplates are original. Thanks for all your help.
