It's funny, well not really, but. I was on the Merrimack River in Hooksett last night with my son on my pwc. We were headed upriver, back to the ramp. There was a ski boat, with a skier down in the middle right of the river. There was also a third boat headed down river. I slowed down and went to the left as far as I could as there was no room on the right. I was about 150' from the river bank on the left, and about 200+ feet from the boat. There really was no where else for me to go. The boater headed in our direction never even slowed down. He flew right between us, although he was closer to me than to the ski boat. I would say he was less than 50' from me, and going about 30-40 mph. This was the same clown I had seen earlier doing circles in his boat, zig-zagging down the river with his kids, wife and dogs in the boat. Arrrgh. Rules? What rules?
