Fact or Fiction: Do All Boats Show as AIS Targets on Radar?
In this latest episode of Icom’s “Fact or Fiction,” Captain Kelly Gordon tackles a common misconception about marine radar systems: Do all boats show up on radar as AIS (Automatic Identification System) targets?
Many believe every vessel on the water appears as those distinctive little triangles on radar screens, representing AIS targets. However, Captain Gordon clarifies that this is a fiction. Not all boats come equipped with AIS. While AIS is prevalent, especially in newer vessels, assuming all radar targets have AIS can be a risky oversight.
AIS systems transmit information such as the vessel’s identity, position, course, and speed, making them invaluable for navigation and safety. However, radar picks up more than just AIS-equipped vessels. Objects like non-AIS boats, landmasses, and other structures can also appear on radar screens. Though not highlighted as AIS triangles, these targets are equally significant and could represent potential hazards.
Captain Gordon emphasizes the importance of not becoming overly reliant on technology. While AIS provides critical information and enhances safety by making vessels visible to each other, it is not infallible. Mariners must remain vigilant and use all available resources—including their own eyes—to navigate safely. “There’s nothing better than a good old set of eyeballs to see what’s in front of you,” Gordon advised. Observing the environment directly, rather than solely through digital displays, remains crucial to maritime safety.
