Cooper Island Beach Resort has a mooring field that is usually one of the first to fill up. In fact most days you must be there before 1:30pm to get a mooring. Of course there are days that you can get one later, but what do you do when you can’t?
Some people try anchoring outside the mooring field. This has two problems. First if you are to the west with the moorings between you and the shore you are getting more and more exposed and bouncing around. Second if you try to find a spot in the bay south of the moorings you will end up drifting into a boat, because the winds are fluky and boats drift here and there and the anchored boats are not far enough away for this.
There is another and better solution. Try Hallovers Bay, which is the bay south of the resort. Here you will find a great sandy area right where the breeze flows over the low area of the island in 15-25 feet of water. The snorkeling in the entire bay is fantastic and the beach is fascinating even though it is not sandy. If you want to go to the resort a descent dinghy can take you around Cistern Rock fairly easily. It is about a mile long ride, although coming back will be a bit bumpy as you come into the wind.
