The Crossing Everyone Wants to Make
Bimini is 50 miles from Miami. On a calm day with a good boat, you can leave at sunrise and be anchored in the Bahamas by noon. It is one of the most accessible offshore passages in the world — and one of the most unforgiving if you get it wrong.
This guide covers what experienced captains actually think about when planning the crossing: the Gulf Stream, weather windows, the right departure point, entry requirements, and what to do when things do not go as planned.
Understanding the Gulf Stream
The Gulf Stream is the defining factor in every Florida-to-Bahamas crossing. It runs north at 2–4 knots between Florida and the Bahamas, and it does not care about your schedule. When the wind blows against the current — particularly when a north or northeast wind opposes the northward flow — the Stream builds steep, short-period waves that can be brutal even on a large vessel.
The rule most experienced captains follow: never cross when the wind has any north in it. A southeast wind of 10–15 knots is ideal. It puts a slight chop on the water but does not fight the current. A northeast wind at 20 knots means the crossing is off, regardless of what the forecast said yesterday.
Choosing Your Weather Window
Do not rely on a single forecast source. Check NOAA marine forecasts, Passage Weather, and PredictWind. Look at the wind direction and speed for the entire crossing window — not just the departure time. The Stream can build seas faster than most forecasts predict when conditions change.
Plan to leave early. Most experienced captains depart between 0600 and 0800 to arrive in the Bahamas with full daylight for navigating the shallow Bahamian waters. Entering an unfamiliar anchorage in the dark or in low light is how boats end up on the rocks.
Build flexibility into your schedule. The best Bahamas cruisers are the ones who are willing to wait two or three days for a proper window rather than forcing a crossing in marginal conditions.
Departure Points
Your departure point depends on your destination and your vessel's speed.
Lake Worth Inlet (Palm Beach) is the most popular departure for boats heading to the northern Bahamas — Grand Bahama, the Abacos, and Bimini. It puts you on a direct line across the narrowest part of the Stream.
Government Cut (Miami) is the standard departure for boats heading to Bimini or Nassau. It is well-marked, easy to navigate at night, and has good fuel and provisioning nearby.
Fort Lauderdale (Port Everglades) works well for boats heading south to Nassau or the Exumas. The crossing is slightly longer from here, but the inlet is straightforward.
For slower boats (under 15 knots), departing from Lake Worth or Fort Lauderdale and heading for Bimini or Grand Bahama keeps the crossing time manageable — typically 4–6 hours in good conditions.
What to Have Ready Before You Leave
The Bahamas requires a cruising permit for foreign-flagged vessels. As of 2026, U.S.-flagged boats must obtain a Bahamas Cruising Permit, which can be purchased online through the Bahamas Customs portal or upon arrival at an official port of entry. Entry fees vary by vessel length. Have your documentation ready: vessel documentation or state registration, passports for all persons aboard, and a float plan filed with someone ashore.
Official ports of entry for the Bahamas include Bimini, West End (Grand Bahama), Nassau, and several others. You must clear customs at an official port of entry before proceeding to other islands. Do not anchor at an uninhabited cay and skip customs — the fines are significant and the Bahamian authorities do enforce this.
Equipment checklist before any offshore passage: working VHF radio (Channel 16 monitored), EPIRB registered and current, life jackets accessible for all aboard, flares current and accessible, anchor and sufficient rode for Bahamian depths (typically 8–15 feet), and a waterproof chart or chartplotter with Bahamian charts loaded. The Bahamas are not well-covered by standard U.S. charts — download Navionics or Explorer Charts before you leave.
Navigating Bahamian Waters
The biggest adjustment for first-time Bahamas cruisers is reading the water. In the Bahamas, you navigate by color. Dark blue is deep water. Turquoise is 6–12 feet. Light green is 3–6 feet. White or tan means you are about to run aground.
This is not an exaggeration — experienced Bahamas cruisers will tell you to trust your eyes over your chartplotter in shallow areas. Charts in the Bahamas can be off by 100 meters or more in some areas. Slow down, post a bow watch, and read the water.
The Exumas are the most popular destination for good reason — 365 cays, crystal water, and some of the best anchorages in the world. But the cuts between islands can have strong tidal currents. Time your passages through the cuts at or near slack water.
If Things Go Wrong
The Gulf Stream is not the place to have a mechanical failure. Before any offshore passage, verify that your engines start and run properly, your bilge pumps work, and you have enough fuel for the crossing plus a 25% reserve. File a float plan with someone ashore who knows to call the Coast Guard if you do not check in by a specified time.
If you do get caught in deteriorating conditions mid-crossing, the safest move is usually to slow down and take the waves at an angle rather than trying to punch through at speed. A 40-foot boat in a 6-foot steep chop needs to be driven carefully, not aggressively.
The Reward
When you clear the Stream on a good day and the water turns from dark blue to electric turquoise, you will understand why people make this crossing every year. The Bahamas are 100,000 square miles of some of the most beautiful water on earth, and they are right in our backyard.
