It has but only for a few short hours lol
The story was that we were fishing a mark called the rips which are about 26 miles out from Poole. We had got there ok with all our electrics working normally however the weather suddenly deteriorated so we decided to about turn and make our way back. At this time our plotter X2 went down and left us with a totally blank screen we also couldn't use the auto pilot. I didn't have a clue what was wrong. Checked connections which were ok, checked trips which were ok and being electrically illiterate at that point I gave up and made a heading at 150 knowing we would hit land and find our way back. Looking around we spotted a naval ship in the distance, it came, it went. After it had gone 3 or 4 miles all our electrics came back to life and back to normal. I can only assume that the amount of power their radar emits blanked out our electrics.
