Frequently Asked Questions

What is your AIS coverage?

UK AIS coverage is neither complete or continuous. There are gaps in the coverage and not all areas are covered 24 hours a day. The map below shows a summary of AIS coverage - darker area have better AIS coverage (and more ships). Gaps in the coverage may be because there are no suitable receivers in the area or because the ships are too far from the coast.
