Destination
Prototype for development purposes only — not for navigation. Ship position, heading, and destination shown here are manually entered test data, not live AIS. Not a substitute for VHF, radar, or a proper lookout, and does not fulfill the Rule 5 (Inland Navigation Rules) lookout requirement. Not a complete catalogue of vessel traffic. Location-dependent and cellular-signal-dependent; will have outage areas. Warns — does not protect.
