There are several ways to track or see our position on line

  • Via AIS. This is a vessel tracking system and we have a "transponder" fitted so other vessels can see our position. Several organisations have set up shore based stations that can track our responder and show the position on a web based map. Coverage depends on them having a receiver near our location. Also unless you pay you can only see our position for a certain time after the event. Web AIS tracking sites include
    • MarineTraffic this is one of the best for coverage
    • Vessel Tracker
    • Vessel Finder
    • FleetMon
    • PortMaps this is a German site but has a nice feature of showing the position on a Navionics Marine Chart
    • APRS.FI This Finnish site is not for profit and run by radio amateurs but it does show you the AIS position for any date, however it does not yet have an extensive receiver network. It also tracks Amateur Radio call signs
  • We may also give position reports by other means, typically using my Amateur Radio Call Sign M0WLH.  There are a couple of ways to do this
    • Winlink (email etc over amateur HF radio) may have a position report associated with my ham radio call sign M0WLH. Usually a position report is sent when we connect to send or receive email or download a GRIB weather map. 
    • APRS, is an Amateur radio tracking service. We can send APRS position reports by a variety of means but APRS.FI picks up  most of them, as well as Winlink position reports. It may also show a position report I have sent on land. It is able to show positions on Google maps or OpenSeaMaps/OpenStreetMaps which may be useful
    • We may be able to send position reports to Yotreps over HF radio  as well. On that site we use the call sign MRGV9.  It will show "No Reports" if there is no recent position report. . The embedded map is below (thanks to this tutorial and using https in the iframe)
