Ever looked at a map? Of course you have. But when you look at a map of United States and Caribbean waters, you aren't just looking at blue paint and green blobs. You’re looking at a jigsaw puzzle where half the pieces are under the sofa and the other half belong to different sets entirely. Most people think of the US and the Caribbean as "The States" and "The Vacations." It’s a lot weirder than that.
The relationship is messy. It's built on centuries of colonial hand-me-downs, weird maritime borders, and the fact that Florida is basically pointing a finger at a dozen different sovereign nations and territories. If you’re trying to navigate this area—physically or mentally—you’ve gotta realize that the lines on the map don’t always mean what you think they mean.
The Invisible Border That Everyone Ignores
Check out the Florida Straits. It's a narrow strip of water. On a standard map of United States and Caribbean regions, it looks like a clear divide. In reality, it’s a high-traffic highway. The distance between Key West and Havana is only about 90 miles. That’s shorter than the drive from Philadelphia to New York City.
Because of this proximity, the US Coast Guard and the Cuban Border Guard have this strange, unspoken dance. We think of borders as walls. Out here, borders are fluid. They’re based on the Exclusive Economic Zone (EEZ). According to the United Nations Convention on the Law of the Sea (UNCLOS), countries generally claim 200 nautical miles from their coast. But wait. The Caribbean is crowded. You can’t go 200 miles in any direction without hitting someone else's "yard."
This creates "median lines." It’s basically the "I’m not touching you" game of international law.
Why Puerto Rico and the USVI Change the Geometry
If you look at the eastern side of the map, you see Puerto Rico and the US Virgin Islands. These aren't just islands; they are the United States' eastern anchoring points. Without them, the US wouldn't have nearly the same claim to Caribbean resources.
Puerto Rico is a "Commonwealth." The US Virgin Islands (St. Croix, St. Thomas, St. John) are "Unincorporated Territories."
What does that mean for your map? It means the US border extends much further south than most people realize. When you are in Christiansted, you are technically in the southernmost point of the United States. You’re closer to Venezuela than you are to Miami. Honestly, that changes how you view the "neighborhood."

The Map of United States and Caribbean Jurisdictions: A Hot Mess
Let’s get into the weeds. You’ve got independent nations like Jamaica, The Bahamas, and Barbados. Then you’ve got the "Overseas Territories."
- The British have the British Virgin Islands (BVI), Cayman Islands, and Turks and Caicos.
- The French have Martinique and Guadeloupe (which are actually part of the EU!).
- The Dutch have Aruba, Bonaire, and Curaçao.
If you’re flying a small plane or sailing a boat, your map is a legal minefield. One minute you’re under US FAA regulations, and forty minutes later, you’re in British airspace. It’s why the map of United States and Caribbean logistics is a nightmare for supply chain managers but a dream for tax lawyers.
The "Third Border" is what US diplomats often call the Caribbean. It’s the idea that the Caribbean isn't just a backyard—it’s a front door. For years, the Caribbean Basin Initiative (CBI) has governed how goods move between these points. It’s not just about cruise ships. It’s about energy. A massive amount of the oil and gas consumed on the US East Coast travels through these Caribbean shipping lanes. If those lanes on the map get blocked, the lights go out in Boston.
The Bahamas and the Continental Shelf
The Bahamas isn't technically in the Caribbean Sea. It’s in the Atlantic. But for any practical map of United States and Caribbean study, they are inseparable.
The Great Bahama Bank is this massive, shallow limestone platform. It’s so shallow you can see it from space. This geography makes the border between the US and The Bahamas incredibly complex. There are ongoing discussions about the exact delimitation of the maritime boundary, specifically regarding undersea mineral rights.
We often think maps are settled. They aren't. They’re negotiated.
How Climate Change is Re-Drawing the Map
Geography isn't static. The Caribbean is arguably on the front lines of the most dramatic map changes we’ll see in our lifetime.

Take a look at the "Sargassum Belt." It’s a massive bloom of brown seaweed that now regularly shows up on satellite maps stretching from West Africa to the Gulf of Mexico. It’s clogging Caribbean beaches and even affecting the Florida Keys. On a digital map of United States and Caribbean environmental health, this is a giant red flag.
Then there’s the sea level.
Many Caribbean islands are low-lying coral atolls. If the sea rises even a few inches, the "baseline"—the point from which maritime borders are measured—shifts. If an island disappears, does the country lose its right to the 200 miles of ocean around it?
International law experts at places like the University of the West Indies are genuinely worried about this. It’s not just about losing land; it’s about losing the legal "footprint" on the map.
The Realities of Travel and Transit
If you’re planning a trip and looking at a map of United States and Caribbean routes, stop looking at the lines and start looking at the "hubs."
Most people think you can easily hop from island to island. You can’t. The map is deceptive. Because of the way colonial history worked, it’s often easier to fly from a Caribbean island to Miami and then back down to another island than it is to fly directly between them.
San Juan, Puerto Rico, is the massive hub for the Eastern Caribbean. Miami is the gateway for everything else.

- Check your documents. Just because an island is "near" the US doesn't mean it’s easy to get to.
- Understand the "Jones Act." This is a weird US law that says only US-built and flagged ships can carry cargo between US ports (like Florida to Puerto Rico). It’s why shipping to PR is so expensive and why the map looks different to a merchant sailor than to a tourist.
- Watch the weather. From June to November, the map is essentially a dartboard for hurricanes. The "Hurricane Alley" usually starts off the coast of Africa and follows the trade winds right into the Caribbean basin.
The Misconception of the "Bermuda Triangle"
We can’t talk about a map of United States and Caribbean waters without mentioning the Bermuda Triangle. Let’s be real: it’s not a thing.
The "Triangle" connects Miami, Bermuda, and Puerto Rico. If you look at the sheer volume of traffic in that area, the number of accidents isn't statistically higher than anywhere else. The insurance industry (Lloyd’s of London, for example) doesn't charge higher premiums for ships traveling through it. The map isn't cursed; it’s just busy.
Actionable Steps for Navigating the Region
Don't just stare at a paper map. If you're actually engaging with the region, you need to think about the layers.
- For Travelers: Use an app like FlightRadar24 or MarineTraffic. You will see the literal thousands of connections happening in real-time. It makes the static map feel alive.
- For Business: Recognize that the Caribbean isn't a monolith. The legal framework of a map of the "region" includes Common Law (British), Civil Law (French/Dutch), and US Federal Law.
- For Geopolitics Junkies: Follow the Caribbean Community (CARICOM). They are the ones actually trying to integrate these map fragments into a cohesive economic block.
The map of United States and Caribbean relations is a living document. It’s about more than just where the sand ends and the water begins. It’s about trade, shared history, and the reality that despite our different flags, we are all sharing the same bathtub.
Understand the "Third Border." It’s the only way to make sense of the neighborhood.
Next Steps for Deep Exploration
- Download Offline Maps: If you are traveling, Google Maps "Offline" feature is a lifesaver in the Caribbean where data roaming is astronomical.
- Study the EEZ Boundaries: Use the NOAA Maritime Boundary Map to see exactly where US jurisdiction ends in the Caribbean.
- Monitor the National Hurricane Center: Keep NHC.noaa.gov bookmarked if you are looking at the map during the summer months; those "tracking cones" are the only lines on the map that truly matter when a storm is brewing.
