On. My way down from Sunbury Lock to Molesey this week I noticed in the distance a boat coming toward me full steam on his port side going up and my starboard going down ! as he was some distance away I felt sure he would notice the error of his ways and crossover to the opposite side of the river but no he just kept coming ! When it got a bit to close to comfort and to avoid a head on collision I was the one that moved over to the Center of the river ! and when we finally passed each other the guy at the helm yelled out at the top of his voice your on the wrong side of the F#####g River !!! I was absolutely Flabbergasted . Now I could understand the situation a little more if the boat in question was maybe a hired boat just out for the day or someone playing blind man’s bluff but this vessel looked to me like a well used 20 ft boat ! So now I’m just wounded if anyone out there in Forum Land can Top that experience .
