Cruising US South & Gulf
The US South and Gulf is thin-water country and the launch pad for the Bahamas. The Florida Keys taper into reef and flats, the Gulf coast's Big Bend is a shallow marsh wilderness, and the Gulf Stream crossing to Bimini is a rite of passage timed around the wind. Hurricane season shapes the calendar June to November. This region covers the Gulf of Mexico, the Florida coasts, and the Bahamas approach, on survey-grade ENC with high-resolution bathymetry offshore.
