Here's another solution; motor until you're out of the park area (they're generally small) then anchor and dink back in. Or, simply move on. There are plenty of attractions to see - no need to get all bent up, especially when on vacation down there <img src="http://www.traveltalkonline.com/forums/images/graemlins/Cheers.gif" alt="" />
Note: I was just there last week (Voyage 600 Jus' Chillin). Our times overlapped at least a little. I never had a problem getting a ball anywhere (Baths, Indians, White Bay, The Bight, Saba/BEYC, etc.).
