I also went through BlueWater like 8 years ago, sailing out of Fort Lauderdale. For my wife and I, it was preparation for our first sail on cruising boats- in the BVI's as a matter of fact. I learned tons from a great captain, the facts as in the books and the attitude and need to pay attention from an experienced sailor. When we finished, our instructor said we were ready for anything we were likely to encounter in the BVI's. He was right. Sailing south Florida with the traffic, the tides, the anchor dragging storms at night, and the more complicated piloting required was a big part of the education. Have fun and, unlike me, read the books before you go.
