Interesting AIS results

Son is currently in Portavogle alongside. Take a look at Beaver Bay on Marine Traffic.

I asked if he was doing manoeuvring trials or if he was at anchor. He's alongside and hasn't moved for a few days.

GPS wobbles or different tracking stations?

Another tidal wave beached them!

You're talking about this track?


Seems totally unremarkable to me. Navigational GPS is only going to be accurate to a few metres, so obviously the trail will mark out a scribble over time.

The tracking station has nothing to do with it since the position is encoded in the AIS message, not measured by the receiver.

He's just popped down to the shops. Nothing surprising there, surely?

Guess so. There no scale on the chart to check (that I have found).

How do you show the aerial view?

if you mean a proper sat view, just go under the + - on the right top there's a folded paper sort of image, click there and select satelite...

A bit of a wobble? My boat is in Torrevieja and Vessel Finder.com is showing the boat is in Amsterdam. The boat was on a Holland flag when I bought it a few month's ago and has since gone onto SSR. Can't understand why it shows up as being in the centre of Amsterdam. I have written to Vessel finder and waiting their reply. Has anyone ever had this happen with a wrong position being given??

You have changed the MMSI to a new one with the reflagging and are merely looking at the wrong (old) Dutch MMSI, which will never be updated again - instead of the new UK MMSI?
