What size anchor ball is standard? This is just for getting off anchor and retrieving the anchor line, not for retrieving the anchor. I bought a 9 inch ball because it's what fits in my locker, but it seems small. In hindsight I guess it really doesn't need to go in the locker.
Biggest ball you can
I've never had my anchor 12" ball go down anywhere around here, if that helps, but it got pretty close in the Keys.
