A few weeks ago I received an interesting email from a Danish sailor. He has given me permission to post it. Tobias wrote:
John,
While finishing your book “Sailing to the Edge of Time” on the way from Sweden back to our homeport Aarhus (Denmark) the attached navigational warning came out of the Navtex. It looks like GPS and other electronic tools are being jammed and are unreliable because of the ongoing conflict in Eastern Europe. I thought it was funny that it came out just when I was reading about GPS in your book. In your books you outline reasons for staying sharp on terrestrial and celestial navigation. I thought I would send this to you in case it could be useful for making the case for nav training in your teaching. Happy sailing and all the best,
