AIS Systems & the New Bahamas AIS Law: What You Need to Know

Automated Identification System (AIS) has become a standard safety feature on recreational and commercial vessels over the past decade. AIS transmits a boat's position, speed, heading, and identification details to nearby ships and shore stations. Originally mandatory only on large commercial vessels for collision avoidance, it's increasingly adopted by private boaters for better situational awareness and security.

Why AIS Matters for Boaters

- Enhanced Safety & Situational Awareness: Track nearby vessels, including those without radar, reducing collision risk.

- Search & Rescue Tool: Activated AIS helps SAR teams locate vessels in distress.

- Marina Security & Monitoring: Many facilities use AIS data to track in/out movements and enforce anchoring rules.

- Regulatory Pressure: As coastal nations tighten safety standards, AIS is becoming mandatory for smaller craft.

New Bahamas Requirement: AIS for Boats Over 50 ft

Starting July 1, 2025, the Bahamas Port Authorities (Amendment) Bill mandates that all foreign

vessels over 50 feet-when entering, docked, traversing, or passing through Bahamian waters-must be actively broadcasting via AIS. The penalty? A hefty $1,000 fine for non-compliance.

Clarification on smaller boats: Initial drafts suggested AIS would apply to all sizes, but a legislative amendment narrowed this to vessels 50' and above.

What This Means for MPI's Boaters

1. Check your boat's length. If your vessel is 50 ft or longer, you are required to install and actively use an AIS transceiver when in Bahamian waters.2. Prepare for installation ahead of time. Current AIS transceivers (like Garmin's AIS 800) run

around $800-1,200-plus installation.

3. Be aware of enforcement and fines. The $1,000 penalty applies per infraction, so ensure your AIS broadcasts at all times.

4. Smaller vessels aren't off the hook. Under-50' boats are not required by this law, but having AIS onboard is still strongly recommended for safety.

5. Plan your cruising itinerary. This new requirement could influence your Bahamas route and gear checklist, especially if your boat's close to 50 ft.

Quick Summary

Vessel Length | AIS Required in Bahamas | Fine if Non-compliant

--------------------|--------------------------|------------------------

50 ft + (foreign) | Yes Yes (actively ON) | $1,000

Under 50 ft | No Not required | -

Best Practices for Preparing Your Boat

- Choose a reliable AIS transceiver compatible with your VHF system and charts.

- Get professional installation to ensure antenna placement and power integration meet regulations.

- Register and test your AIS-verify your MMSI is programmed and confirm unit broadcasts correctly.

- Monitor AIS while outside Bahamas to ensure your gear activates when entering and remains

functional during your trip.

- Inspect AIS routinely-regular checks prevent last-minute failures or surprises.

Final Thoughts

The Bahamas' new law underscores growing global expectations for marine transparency, security, and environmental awareness. For MPI boaters, compliance means:

- Smooth, worry-free cruising,

- Avoidance of steep fines ($1,000 per infraction), and- Enhanced personal and maritime safety.

Even if your boat is under 50 ft, AIS offers multiple safety benefits-definitely worth considering as part of your navigation upgrades.

Stay compliant, stay safe, and enjoy clear waters ahead!
