The anchor retrieval ball will work great!!! Anywhere even in the Bahamas. I used to do it all the time. I finally got a windless so I don't use it as much.
Here is a link to one
Anchor Retrieval System.
You can make your own, isn't much to it. What is amazing is how well it works. I had never heard of it until I ran into a commercial fisherman that uses it. I thought he was crazy. Soooo When nobody was around I tried it. Holy Mackerel Andy worked like a charm.
