Tracking our movements
Catharina Elisabeth’s Automatic Identification System (AIS) device continuously reports our position using VHF radio to ships around us as we travel but when we are close to some land-based receiving stations, our position can also be reported to the internet. on busy waterways. These receiving stations are generally located near busy waterways, capture our AIS transmission and connect to databases like those hosted by Vessel Finder and Marine Traffic via the Internet. Most of these internet-connected receivers are run by volunteers and, especially in France, are few and far between. So, over a lot of our cruising range, even though our AIS is continuously reporting our position, it does not get posted to the Internet, and Catharina can’t be located.
In the maps below, our position may be out of date. Times on the map are UTC (Greenwich Mean Time), which is two hours earlier than Western Europe in summer.
