You can get stop/boarded for basically any reason they want to come up with.(articulable suspicion seems to be "the phrase"

)
I don't care if they stop me. Zee paperwork is in order, I have ALL the necessary safety equipment on board for lake OR ocean, I don't drink, and I KNOW I am more knowledgeable than most(I have the Tres Martin diploma, power squadron cert(s), dunk-tank cert, etc etc) and am a safe and excellent driver.
It is an inconvenience only. The NHMP are a bunch of pretty good & fair guys.
I am GLAD they are out there watching for articulable suspicion.
