2. AIS Requirements for Charter and Commercial Vessels

AIS (Automatic Identification System) allows vessels to transmit position, speed, and identity information to nearby vessels and shore stations.

The U.S. Coast Guard regulates AIS under 33 CFR Part 164.

When AIS Is Required

AIS is generally mandatory for:

• Commercial vessels over 65 feet
• Passenger vessels carrying more than 150 passengers
• Certain towing vessels
• SOLAS vessels operating internationally

Even when not required, many charter operators voluntarily install AIS to increase visibility and safety.

AIS Classes

Class A — Required for larger commercial vessels

Class B — Common on recreational and small commercial vessels

AIS also integrates with Vessel Traffic Services systems.
