Cruising Caribbean
The Caribbean is reef country, and the difference between a perfect day and a holed hull is often a single uncharted coral head. This region spans the Bahamas banks, the Greater and Lesser Antilles, and the Central American coast, built on survey-grade ENC where available and high-resolution bathymetry elsewhere. Eyeball navigation still rules the final approach, but depth-aware routing and accurate hazards get you safely to the cut.

Questions
Are Caribbean reefs and coral heads charted?
Hazards, wrecks and obstructions are included from survey-grade charts and community reports, but reefs shift — always keep a lookout on final approach. The chart gets you to the cut safely; your eyes do the last hundred metres.
Does it cover the Bahamas banks?
Yes — the shallow Bahama banks, the Exumas, and the cuts are covered, with depth-aware routing that respects the thin water.
Will it work without cell signal between islands?
Yes — fully offline once downloaded, which is the norm on a Caribbean passage.
