On a recent sar mission, I was navigating and the chart plotter software crashed and had to be restarted, we had no electronic charts for 5 minutes at 20kts, we were losing primary GPS intermittently, meanwhile it was hard to read the radar picture reflected from the coastline as the sea filter had to be turned right up due the heavy and confused seas. The depth sounder was intermittent as we were getting some air every time we went over a wave. You can be damn sure I had the paper charts out and I was regularly logging our position on paper and keeping track of all the navigation marks we could see out the window when it wasn’t covered in spray.
