anyone here even contemplating the idea of shouting warnings at pirates is either:
A) NEVER been on a boat before
B) living in a dream world
would you shout at the taliban? "stop please or i might shoot at you"
unless your in the middle of still calm water, with no wind and about 50 metres apart with no engines running, your not going to hear **** all.
even if YOU could, do you think the pirates are going to hear your little yelping over the sound of a pair of **** off great outboard motors? and if they do hear you, are they going to care?
and if they are within earshot, then youve already ****ed up. there are no set rules for what range you should fire warning shots but common sense says if their close enough to shout at, then their close enough to raise their weapon and fire several shots straight into your face and chest as your busy shouting at them.
hope that answers your questions
