It seems the state vs. boat-ed/NH have different meanings of "rafting". I remember when I took the Boaters Safety Course for NH that "rafting" was defined as "3 or more" boats and that is what I studied and had the the test. Looks like the state has the same understanding. But in the last 2yrs., the boat-ed/nh has it defined as "2 or more" boats as well as the MP. Which one is it?
