1/4" or 5/16"? Which grade? Breaking strength?
Seen lots of discussion around the length of chain and type of anchor, but not as much around the minimum chain to use.
5/16 is a lot more expensive than 1/4, so I'd want to get away with that if I can...

It is sized by the requirements of your windlass, which I don't recall. But the chain links have to fit properly into the windlass. The C36 owners manual or the windlass manual will say.

David, in addition to yoru discussion with Larry, here is some information that may help you make your decision:

Of course, your chain has to fit your windlass.
The length of chain has always been suggested to be a minimum of the boat length, but as you'll see in the link, one of our skippers (who has a windlass) came up with a great idea about a longer amount of chain deployed with a short amount of rode to avoid having to add snubbers, making it essentially an "all chain" system without the hassle of snubbers.

My Maxwell Freedom 800 windlass specifies 5/16 chain and 5/8" three strand.
I'd go with G-40 chain for strength also.

I also have the Maxwell 800. The manual specifies "up to 5/16" chain. Has anybody tried this windlass with 1/4" chain?
I plan on buying the high-strength stuff. Will 1/4" be sufficient given the displacement of our boats, and the fact that I'm unlikely to anchor in anything over 15 knots?
I should probably just bite the bullet and spent the extra $150 or so for 5/16" in the length of chain I'm buying...

David, as far as strength, here are charts/tables and a discussion of the selection of the components of an anchor SYSTEM:

Of course, your windlass gypsy will be the determining factor. I've rarely heard of a gypsy being good for chain "...up to" a certain size, I always thought they were made for a specific size, and also important, type of chain.

Stu; I always thought the same. But my Maxwell VW1500 manual specs say the same thing; 'for chain from 1/4" to 3/8"'. And it only lists one part number for the 'chain wheel'. Yet it also says to match the chain to the wildcat (gypsy). I'm about to go to a mostly chain rode, and I think I'm going to disassemble the windlass and take the chain wheel with me so I can be sure that 5/16" chain fits properly. The manual is definitely confusing.

Gary, when we bought ours we were told it came with the 5/16 gypsy but it showed up with a 3/8 one. Maxwell emailed me a spreadsheet with all the gypsy wheels listed and told me to pick one, which they then shipped me with a return label for the 3/8 gypsy. There was an extensive list of chain wheels.
