Beginning *July 1, 2025, every foreign pleasure vessel 50 feet (LOA) or longer entering, cruising, anchoring, or even tied to a dock anywhere in Bahamian waters must keep a functioning Automatic Identification System (AIS) turned ON at all times—or risk a $1,000 fine per infraction.
Quick-Hit Facts (Read This Before You Cast Off)
- Effective date: July 1, 2025
- Who’s covered: Foreign vessels ≥ 50 ft LOA (sportfishers, trawlers, yachts, live-aboards, delivery transits)
- Penalty for non-compliance: Up to $1,000 each time AIS is off or missing
- Always-on rule: AIS must transmit whether underway, anchored, or docked
- Small-boat note: < 50 ft are exempt—but safety agencies still “strongly recommend” AIS for everyone
Why Did the Bahamas Tighten the Rules?
The Port Authorities (Amendment) Bill 2025 is part of a broader safety, conservation, and revenue overhaul. Parliament cited congestion around high-traffic islands, illegal fishing, and SAR (search-and-rescue) delays as primary drivers.
According to International Maritime Organization (IMO), worldwide AIS adoption has soared—220,000+ commercial and leisure boats carried transceivers by late 2024, up nearly 35 % in three years.
The Bahamas wants every sizable visiting boat on that grid to improve situational awareness and enforce new anchorage, fishing-permit, and seabed-lease rules.
Who Exactly Must Comply?
| Vessel Length (LOA) | AIS Requirement July 1, 2025 | Non-Compliance Fine |
| ≥ 50 ft (foreign) | Mandatory – unit ON 24/7 | $1,000 per violation |
| < 50 ft (foreign) | Optional but recommended | – |

AIS 101—What It Is & Which Type You Need
AIS is a VHF-based transponder broadcasting a vessel’s MMSI, position, course, and speed every few seconds. Shore stations and other boats “see” you on their plotters, radars, and smartphone apps.
| Feature | Class B (Most Pleasure Craft) | Class B-SO (B+) | Class A (Commercial) |
| Power Output | 2 W | 5 W | 12.5 W |
| Reporting Rate | 30 s (typ.) | 15 s | 2-10 s (dynamic) |
| Target Range | 5-8 nm | 8-12 nm | 20-25 nm |
| Cost (hardware) | $700-$1,200 | $1,100-$1,700 | $2,500 + |
| Bahamas-legal? | Yes | Yes | Yes (overkill for most) |
For most 50- to 80-ft Florida-based cruisers, a Class B or B-SO transceiver satisfies the new law and integrates seamlessly with Garmin, Raymarine, Furuno, or Simrad networks.

Step-by-Step: Getting AIS-Compliant Before You Cross the Gulf Stream
- Measure & document LOA. If you’re 50 ft or more (including pulpits & platforms), AIS is mandatory.
- Choose the right transceiver. Class B or B-SO meets Bahamian specs; verify NMEA 2000 or 0183 compatibility with your helm.
- Obtain/verify your MMSI. U.S. boats bound internationally need an FCC-issued MMSI (not the free BoatUS number).
- Schedule professional installation. Proper antenna siting, VHF splitter, and GPS feed are critical for full-power broadcasts.
- Register the unit & test. Use an AIS website (e.g., MarineTraffic) or a buddy boat to confirm your signal before departure.
- Print proof. Keep your installation invoice and MMSI registration in the ship’s papers for customs officers.
- Leave it on. Once you sight the Bahamian banks, AIS stays broadcasting while underway, at anchor, and tied to the dock.
Other New Rules You’ll Brush Against
- Hikes cruising-permit fees (e.g., $1,000 for 34-100-ft boats)
- Introduces a Frequent Digital Cruising Card (FDCC) for multi-trip skippers
- Adds anchorage fees for boats that forgo marinas
- Strengthens seabed-lease enforcement near reefs and beaches
While those topics deserve their own article, AIS is the single piece of gear now required for many winter snowbird boats.
Common Misconceptions—Busted
- “I’ll turn AIS off once I’m at the dock.” Illegal. The law specifies “turned on whether docked, traversing, or passing through.”
- “My 49-footer with a swim platform doesn’t count.” Customs measure total length overall; swim platforms can tip you over 50 ft.
- “A receive-only AIS app on my iPad is enough.” No—transceiver required. Apps don’t broadcast your position.
- “Class A is safer.” Not necessarily. Class A requires unique interfaces and higher install costs; Class B-SO meets the rule and integrates with typical yacht networks.
Key Takeaways
- July 1, 2025—effective date date.
- ≥ 50 ft foreign boats = AIS ON 24/7 in the Bahamas.
- $1,000 fine each time customs catches you dark.
- Class B transceiver covers 99 % of pleasure-yacht scenarios.
- Early compliance avoids rush-season backlogs at Florida yards and Bahamian check-in points.
