That's a good one JB - must have been a very interesting trip - only similar one I can recall was the US sailors who bought a Landing Craft
- not sure which version
maybe a LCT - and sailed it all the way back to the USA from the Med somewhere shortly after WW2. Not one of them was a deck officer.......
All I know is the modern sailors could not cope without their gadgets - forgetting that in the vastness of the sea things can break and electronics stop working - and they would not even carry a sextant
or know how to use it
Slocum used an old alarm clock and the stars to navigate by, my Dads pal Harry Pidgeon used a sextant
but still managed to run aground about 120 miles up the west coast from Capetown while asleep - had to be towed +-300yards back to the sea by a team of oxen - no leaks so Islander must have had a tough hull.........
