Anchor Chain size differences

svmariane · 15-07-2007, 11:26

What's the actual link-length for 1/2 inch Proof Coil vs 1/2 inch BBB anchor chain? I'm in Mexico and DON'T want to special order the wrong stuff!

For the curious: I've 200 ft but want 350 ft overall chain length for my main anchor. The genius who previously owned my boat filed and hacked the capstan gypsy to accomodate the current 1/2 inch chain - which works really well. However, the gypsy has 3/8 PC stamped upon it - which doesn't help me.

Answers or even pointers to info would be appreciated!

Aloha James,
Welcome aboard!! Good to have you here. I'd like to see a photo of your boat. I baby sat a Celestial 46 ketch for a year and did some sailing with it in Hawaii. Maybe it was a 48? Hard to remember. Many years ago. It was a very nice boat.
Kind Regards,
JohnL

Aloha again James,
I did find the picture of your boat and it dows look like my friends boat. I didn't remember his having a reverse transom though.
Kind Regards,
JohnL
