Tracking Sancerre

When the satellite link is active the location and recent track of Sancerre, sometimes with comments, will show in the window below (marked "Predictwind"). To keep cost down I only activate the system during the summer when I am likely to need met reports or email etc. by satellite so check the last reported date, bottom left.

For a larger version in a new window click this link. I have noticed that sometimes the in-line version is not always updated correctly a "refresh" normally sorts that but the larger version is recommended, notes (if any) are also less intrusive.

The position and recent track as reported by AIS (Automatic Identification System) should be shown on one or all of the imbedded maps at the bottom of the page. Alternatively larger versions can be viewed by going to the respective web sites, or All open in new windows, the various sites have different populations of AIS receivers so one may pick me up when the others don't, also they have different charging systems so the free versions have varying amounts of historical and other information. appears to have the best coverage but subscriptions are expensive and historical info on the free version is limited (a cheap one off purchase of the iPad app improves that somewhat giving a >= 24 hour track on the iPad and PC using the same sign-on). 

"Vesselfinder" and "Myshiptracking" frequently give a very out of date report, clicking on the panel (eg on "more info") may bring a later position.

All of them should always give my latest position if in range of one of their stations and that will normally be updated every few minutes whereas the IridiumGo track, when active, is updated every hour and appears not to be as accurate (I think this is a plotting issue not the position report itself). Note that I turn my AIS off when in harbour or a safe anchorage so that the reported time in port will be a about the time I arrived there. In some open anchorages, those close to a fairway or in poor visibility I may leave the system on so that ASI equipped vessels will have warning of my presence.

Iridium was reactivated on Friday 8th April 2022, tracking started on the 9th from St Michael's Mount, Ignore the line from NE England which is were I was when I switched it off last year.

Deactivated 27th May
