Rode and chain

[Cymru]

Hi all,

Hope everyone is having a safe a happy summer!

I have to change the anchor rode on my 2001 2900SCR but for the life of me, I can’t make out if its 1/2" or 5/8". It's the oem Lewmar windlass. I boat on an inland lake so tides, etc are not a worry so I don’t think I need stuff just to over compensate like I would do if I were on the ocean.

Any ideas what it should or can be?

Thanks.
