I was about to order some 316 SS flat bar today to make up my new chain
plates. Since almost everyone of my old chain plates (both mizzen and main)
are at least a bit bent, I am thinking that they were undersized to some
extent( or my boat got beat up in some nasty storm!!)My mizzen chain plates were .1875″ x 1.25″. As a minimum, I am going up to
.25″. Almost the same cost and will fit no problems. Has anyone gone one
further size up to .3125″ (5/16 ths) for the mizzen.My main chain plates were .375″ x 1.5″. The next size up is .500″. This
wouldn’t cost a lot more (<$100 total more) and would fit the toggles okay.
Some additional work would be required enlarging the slots in the deck. but
that should be pretty easy with a dremel tool. My surveyor, who had owned a
424 for 13 years, indicated that he went up to 1/2″ plates on his boat. Have
many others done the same or just stayed with 3/8″??Thanks,
Paul

If you're doing the job now and the incremental cost isn't that great, do it. It will help if you ever sell the boat.

Hello Paul,
I just finished replacing the chain plates on Indulgence. I did not go up in size. Please make sure the covers will fit over the lager width chain plates…the covers on Indulgence are pretty close fitting and probably would not have fit using the increased width.
The project was more time consuming than I had thought. I had all the chain plates cut to the same size and with no bends. Fort the most part, everything went back together nicely.

Actually Walter, I suspect our chain plates came out of the machine shop on the same day. We'll never know which ones were cut from the stock first. I did a visual inspection on my chain plates – no sign of water intrusion nor of corrosion. I re-bedded the cover plates last summer after the sail back from Europe. I will replace those chain plates prior to another long passage as I'm now less concerned about corrosion as I am about metal fatigue.

I took all of mine out, Inspected them, had them inspected by a machinist (just in case) and put them back in with new bolts. No corrosion, no signs of stress.
I assume they are original, and arguably the oldest ones out there.
