I kayaked alot years ago. I always had it figured that since I didn't need much water to float the thing. I was always out of the channel. Sometimes you have to cross a channel to get to where you were going. I also wore a bright red paddle vest. The paddle was bright yellow. I wanted folks to see me out there. It is much like the bicyclers who block off the road and back up traffic. Sure they have the right of way according to the law. Doesn't mean it is a good idea to push ones luck. Make enough of a nuisance of your activity and you usually lose the right to do it. The main reason I always tried to stay out of the way. Doesn't hurt to share the water or the road. But it is a double sided coin
