The stretch of the Sudbury River that passes our house is designated a Wild and Scenic River of Massachusetts. It is a favorite of kayakers, canoers, and paddleboarders who are drawn to the peaceful and nature-laden shores. Fishermen also ply the river and often arrive in small boats powered by electric motors or small gas outboards. Occasionally, we see recreational boaters who prefer going fast above all else. While they have every right to enjoy the river along with all others, I fear that one day there will be a collision between fast and slow. I am trying to determine if there is a speed limit for his part of the river. I remember reading somewhere that there is a no-wake rule and in another that the limit is 10 mph. If a limit exists, the next step would be to post it. Bridges across the river would offer the perfect place to do so.
