Great shot of the boats skimming over the crystalline waters... very nice!

2 of the Bahamian C-class boats, sailing through the anchorage, on their way out to the race course.

Human ballast.  You need to see this on the larger A-class boats when they have a bunch of people out on the boards.  

When they tack, the ballast has to be moved to the opposite side... and quick!

These are all full keel, traditional wood boats using rocks in the bilges for their none moving ballast.

A beautiful thing to watch...
