The live Oyster Owners AIS map is an exclusive feature for Oyster Owners. Providing your AIS transponder is switched on and you are within one of the many hundreds of AIS stations around the globe, your position will be displayed on the map. If you turn your transmitter off or move out of range of a station, your last reported position will be displayed. Use the buttons on the left of the map to turn various layers on and off. Please enter your own MMSI number in your profile here.
