I received as a present for Christmas, a copy of A World of My Own: The First Ever Non-stop Solo Round the World Voyage which was written on his return by the sailor Robin Knox-Johnston.

It was a gripping read, even though of course I know the ending (you know that Knox-Johnston was the first person to single handedly sail around the world – right? Francis Chichester in Gypsy Moth IV sailed round singlehandedly, but with a stop in sydney.

This does really make a difference, for much of the journey Knox Johnston had no radio contact with the outside the world, although he could recieve transmissions, he couldn;t tell anyone that he was still fine and out there, relying on contact with a handful of merchant ships to give updates on his progress. And this was before GPS – so he was using Sextant and Chrononometer to tell where he was.

Its not quite enough to make me leave for the sea, but I do plan to carry on self medicating on that score. Whilst sailing this october, One afternoon, instead of doing what I should have (sleeping) I spent much of the 12-4 watch with the 2nd officer getting some bits of my training book signed off, and also getting the idea into my head to learn about astro navigation – tough going just to get a basic understanding of the principles, next off to learn how to use a sextant and then I just need one to try it out on, and the data to use with it
….

 

I was aware of a problem with the way in which Garmin saves historical tracks, in that it strips out the time stamping data, and this makes it no use for OSM, (or I guess for geotagging photos either.)

The good news is that this does not apply to the tracks that are automatically stored on an inserted Micro SD card, at least not in my Vista HCx. I have set my unit to log to the card as well as its internal memory. When accessing my tracks using the mapsource manager i only access the current track, but if i put the GPS into USB Mass Storage mode, then i can browse a series of tracks, with one .gpx file per day.

I have pulled back these tracks, and successfully managed to upload one to the open street map.
