Just to set your mind at rest, we are not moving into Vagabond whilst she is parked in the barn at Kings Ash Farm. (Not ever, I hear the Owners Agent asserting very firmly.)
As a bit of light relief, I have discovered that I have recorded most of the track that Vagabond follwed this summer and that I can display them on a PC. So now you can be amazed by this technology as I publish these tracks over the next few weeks. You can re-live each leg and refer back to the blog of the day!

The third snag is that the Ipad does not communicate with any other instrumentation - I daresay you could do it using the wireless interface but that is (a) beyond my competence and (b) would use even more precious amps.
So I have a second GPS, the Garmin 620 already discussed. This serves as a back up to the IPad, as it takes its power from the main batteries and, as I have discovered, records the track.
It talks with the VHF, to give it the GPS details for the dreaded DSC Mayday call, and also listens to the radio information on AIS data from other ships. When the radio identies a potential "target", the GPS displays them and it shouts at you if they are dangerous. Usually this warning is very pessimistic and can be ignored once one has identified the target although it did make me wake up when one of those fast catamaran ferries snuck behind us near Poole.
As originally fitted, there was a TackTick wind sensor at the mast head, communicating with a Tactick display. This also receives Sog and Cog from the GPS so can show both relative and true wind speed and direction. It's blank in the photo above, showing that the picture was taken after the sensor had been blown off.
Finally, there's a TackTick depth display. On a couple of occasions (when sailing very quickly) is has shown spurious results.
The ship batteries are topped up by a couple of solar panels mounted on the poop. I have not yet exhausted the batteries during a cruise but have only been away from shore power for a couple of days at the most.
