Whilst I still can't find any mention of gunfire in the COLREGS as a valid alternative to five blasts on the horn (though god knows many skippers have felt like it), I do have sympathy with any officer of the watch faced with a yachtie who thinks two degrees is "an obvious change of course"
The retired couple tell BBC Newsnight they tried to show the warship they had changed course in the English Channel before the shots were fired.
