AIS transponders are required on all ships over 300 tons when operating internationally and 500 tons when operating domestically. Passenger ships are required regardless of their destination. This means that nearly every commercial vessel will have one. In addition, many yachts and other vessels voluntarily carry an AIS transponder. Each year more and more vessels are equipped with AIS because of the significant safety benefits.
