GBG, I know you, and am sure you did politely ask that the fisherman cast away from your boats. His reply was obviously born of ignorance and an entitled mentality. If he does it again why don't you pull your own rod and reel out and cast a few in his direction. Turn-around is fair play. Most fisherman I have encountered at our shores have been very conscious of our property, but it does only take one to spoil the pot.
