Continue your journey with these curated navigation guides.

Confused by the alphabet soup of marine AIS? We explain the technical differences between Class A, Class B, CSTDMA, and SOTDMA so you understand exactly how commercial ships see your yacht.

From silent electric propulsion to MARPOL-compliant waste systems, learn how to navigate the shift toward a zero-impact marine lifestyle without sacrificing performance.

A complete expert guide to sailing the Cyclades — covering routes, anchorages, meltemi winds, passage timing, and island-by-island navigation intelligence for the Aegean Sea.
The sun hasn't quite broken the horizon over the Windward Islands, but the sky is already a bruised purple. I’m standing on the sugar-scoop of a 45-foot catamaran, the cooling trade winds—the Alizés—tugging at my rigging. Above me, the Navionics plotter in the cockpit glows with a dim red night-filter, showing a jagged coastline that most cruise ships wouldn’t dare approach.
This is the reality of the Caribbean that isn't on the brochures. It’s not about the bustling marinas of Tortola or the crowded bars of English Harbour. It’s about that moment when you drop 50 meters of galvanized chain into five meters of gin-clear water, feel the Rocna anchor bite into the primary sand, and realize yours is the only mast in the bay.
As an RYA Yachtmaster with over two decades of blue-water experience, I’ve learned that the "hidden" spots aren't hidden because they’re invisible; they’re hidden because they require a level of navigation and respect that keeps the casual sailor away. This guide gives you the charts, the anchoring specs, and the first-hand waypoints to get there safely.
About this anchorage guide: Every location in this list was visited and anchored in by Captain Jack across multiple seasons of Caribbean cruising (2018–2026), covering the Grenadines, the Leeward Islands, the Spanish Virgins, and Tobago. Depth, holding, and approach notes are based on first-hand anchoring experience cross-referenced with current Imray Iolaire charts. Disclosure: No marina, charter company, or tourism authority compensated BoatGuider for any listing in this guide.
Before we dive into the coordinates, we need to talk catenary. The Caribbean isn't just a destination; it’s a weather system. You are anchoring in the path of the relentless NE Trades. If you aren't prepared for the "Christmas Winds"—sustained 25-30 knot gusts that can last for days—you'll find yourself dragging toward a lee shore of volcanic rock.
In most of the anchorages listed below, you’ll be anchoring in 4–10 meters of water. My standard RYA protocol is a minimum of 5:1 scope for all-chain rode in calm conditions, and 8:1 when the swell starts rolling in from the Atlantic. If you’re using an older CQR or Danforth, double your vigilance. Modern high-holding anchors like the Spade or Mantus are the gold standard for the hard-packed sand and seagrass commonly found in the Leewards.
| Anchorage Component | Yachtmaster Professional Specification | Key Requirement |
|---|---|---|
| Primary Anchor | 33kg Rocna / Spade / Mantus | High-holding power in sand/grass |
| Rode | 100m Grade 40 Galvanized Chain (10mm) | Catenary weight is life |
| Snubber | 10m 3-strand Nylon (16mm) | Shock absorption for trade wind gusts |
| Electronics | Raymarine/B&G with forward-scanning sonar | Essential for coral-head avoidance |
| Charts | Imray Iolaire Paper + Navionics Digital | Cross-reference is mandatory |
The Grenadines are the crown jewels of Caribbean sailing. Navigation here is purely visual; you are reading the color of the water more than the depth sounder.
While the southern end of Mayreau is a tourist hub, the true magic lies in the northern pocket of Salt Whistle Bay. You need to approach with the sun behind you to spot the reefs.
Most boats group together inside the Horseshoe Reef. For the true Yachtmaster experience, navigate further east to the Sandbore.
Frequently bypassed for the "shallows," Chatham Bay offers the best protection in a "Northie" (a northern wind shift).
| Grenadines Data Table | Protection | Best Holding | Depth (Avg) |
|---|---|---|---|
| Salt Whistle Bay | NE / E / S | Pure Sand | 4m |
| Tobago Cays | NE / E | Sand & Rubble | 3m |
| Chatham Bay | All but NW | Sand/Grass | 7m |
| Petit Nevis | NE / E | Sand | 6m |
As you move north from Martinique toward Antigua, the geography shifts from coral cays to towering volcanic peaks.
Just a few miles south of Fort-de-France, Anse Noire is a black sand pocket surrounded by sheer jungle cliffs.
Dominica is the "Nature Island." There are no marinas here. You use the P.A.Y.S. (Portsmouth Association of Yacht Services) moorings or drop anchor in the deep Soufrière bay.
Antigua has 365 beaches, but Deep Bay holds a secret in its center. The wreck of the Andes, an 1874 merchant ship, sits in just 4m of water.
| Leeward Island Specs | Bottom Type | VHF Contact | Protection |
|---|---|---|---|
| Anse Noire | Volcanic Sand | N/A | NE / E |
| Soufrière (DOM) | Boulders/Sand | Ch 16 (P.A.Y.S) | All but W |
| Deep Bay | Hard Sand | Ch 68 (Antigua Radio) | All but W |
| Colombier | Sand | Ch 16/12 | NE / E |
The Virgin Islands are often dismissed as "Charter Central," but the Spanish Virgin Islands (Culebra/Vieques) tell a different story.
Not to be confused with the main harbor on Culebra, Culebrita is a nature reserve.
Only a mile from the chaos of Tortola, Guana Island is private, but the seabed is public.
Accessible only by boat or a long hike, this is the quieter side of the "Billionaire's Island."
For the truly adventurous, head south to Tobago. Man-O-War Bay is a vast, primeval amphitheater of green.
In the Caribbean, your backup plan is your primary plan. On my boat, POSEIDON, we never trust a single source.
| Equipment Master List | Recommended Model | Yachtmaster Rationale |
|---|---|---|
| Chartplotter | B&G Zeus 3S | Unrivaled sailing software |
| AIS | Vesper Cortex | Smart transponder with VHF |
| Handheld VHF | Icom M94D | Built-in DSC and GPS for dinghy |
| Binoculars | Steiner Navigator | Stabilized optics for spotting marks |
| Pilot Book | Chris Doyle Guides | The "Bible" of the Caribbean |
If things go wrong—and they eventually do at sea—knowing who to call is the difference between an inconvenience and a tragedy. Don't rely on cell service.
| Rescue Authority | Location | VHF Channel | Emergency Number |

| VISAR | British Virgin Islands | Ch 16 | +1 (284) 499 0911 |
| MRCC Fort-de-France | French Antilles | Ch 16 | +596 596 70 92 92 |

The hidden anchorage isn't just a place to park your boat. It’s a mental state. When you sit on deck as the stars begin to populate the Caribbean sky, with the nearest neighbor five miles away, the noise of the modern world disappears.
You aren't just a visitor; you are part of the ocean's rhythm. You’ve successfully navigated the reefs, trusted your gear, and been rewarded with a slice of the planet that few will ever see. This is the reason we buy boats. This is why we study the charts.
The Caribbean isn't becoming smaller; we’re just becoming more afraid to explore it. Pack your Rocna, update your Navionics, and leave the marina behind. The hidden gems are still there, waiting for those with the courage to drop anchor.
"To reach a port we must sail, sometimes with the wind and sometimes against it. But we must sail, and not drift, nor lie at anchor." — Oliver Wendell Holmes
In the Windward Islands (especially St. Vincent, the Grenadines, and Dominica), you will be approached by local entrepreneurs in colorful plywood boats, commonly known as "Boat Boys."
These men are not panhandlers; they are mobile service providers. They offer everything from fresh bread and ice to "custom" mooring buoy assistance.
When going ashore in remote villages, remember that you are in someone’s backyard.
Culebra and Vieques (the Spanish Virgins) offer some of the most pristine anchorages in the Caribbean, but they come with a technical navigation challenge: Unexploded Ordnance.
For decades, the US Navy used Vieques and parts of Culebra as a bombing range. While the range is closed, the seabed in some areas is still "Littered" with old shells.
In many volcanic islands (like Martinique or Dominica), you will find yourself anchoring in 60 feet (18 meters) of water or more. This requires a different technique than the shallow sand flats of the Bahamas.
If you are exploring the hidden spots, you need to be self-sufficient.
Many remote islands (like Anegada or Mayreau) have limited fresh water.
Fuel in remote areas is often dispensed from 55-gallon drums on a rickety pier.
The Caribbean is still the greatest cruising ground on earth, but only if you have the courage to leave the "Charter Track." By mastering the Deep Water Set and respecting the Boat Boy Economy, you unlock a level of freedom that most sailors only dream of.
I'll see you at the ramp!
