This was the first trip on which I used my new Canon Powershot D20 camera as a "trip log". The camera is waterproof and has GPS logging even when switched off. The idea is that I take photos at intervals and these are recorded with the GPS position. If the Garmin chart plotter stopped working the last photo would give me a position that I could mark on the chart. Also the camera GPS log gives a track record independent of that logged by the Garmin. The photos often will not be any good, but they will show where I was!
