Don't do it. I took their course in Tampa Bay 20 years ago, then took the family on a bareboat charter in the BVI. After that experience, we kept coming back every year. Then we chartered in other Caribbean locations. Then we bought a boat and put it in charter, with ample owner's time. Then we started annual 2-month summer excursions down-island (and return). You don't want to get addicted like us.

Seriously - their course was an excellent preparation for bareboating, but the real education comes from time on the water.
