Anchor AlarmCaribbean Sea charts — built for how you actually cruise
Bahamas to the Grenadines — reef-strewn water that demands a real chart.
Popular sailing destinations
Where this region's sailors actually drop anchor.
British Virgin Islands
The world's easiest line-of-sight cruising ground — and the busiest charter base. Mooring fields everywhere.
The Grenadines
Tobago Cays, Bequia, Mayreau — reef anchorages that reward careful pilotage.
Exumas, Bahamas
Gin-clear shallow banks where charted depth is everything. Tidal cuts run hard.
St. Lucia & Martinique
Volcanic anchorages under the Pitons; an easy reach down the island chain.
Antigua
English Harbour, Falmouth, and 365 beaches — the hub of the eastern Caribbean season.

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.

Tides & currents
Tidal heights and streams, bundled in.
Rocks, wrecks & hazards
Charted obstructions so you can plan a clean approach.

The Caribbean pack is built from NOAA's official Electronic Navigational Charts — the federal survey data itself — fused with community-verified rocks, wrecks and navaids, then packed to work with no signal.

The source, not a copy
NOAA and USACE publish their charts as S-57 ENC cells. Our pipeline parses those cells directly, so depth areas, soundings, wrecks, rocks, channels and aids to navigation arrive as the hydrographers surveyed them — never traced off an image.
The paper chart is gone
NOAA finished cancelling its traditional paper and raster charts in January 2025. The ENC is now the only official US chart there is, which makes reading it properly the whole job rather than a bonus feature.
Public data, honest price
US government charts are public domain and carry no licence fee. That is why a US region is $14.99 a year flat — charts, depth-aware routing, tides and seabed included — instead of a chart licence billed on top of the app.
Government-charted regions
Source data: NOAA Office of Coast Survey and the US Army Corps of Engineers, in the public domain. AnchorQueen is an independent product, not affiliated with, endorsed by or certified by NOAA, USACE or any US government agency. Region packs are derived charts for situational awareness and do not replace the official charts a vessel is required to carry.
Anchoring in Caribbean
AnchorQueen is an anchor-watch app first. Every Caribbean chart carries seabed type and holding quality from official survey data, so you read the bottom before you drop the hook — then the anchor alarm watches your swing while you sleep.

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.
