On Winnipesaukee, the MP has those three 27' military style, combo aluminum-rib interceptors, powered by twin Merc 150 two-strokes, two marked & one unmarked. Mostly, they just slowly cruise around at about 1/4 power, just being present, visible, and available in case something happens. They like to set up and wait in some likely spot, behind a little island or around a bend, and anticipate for something to happen. It's called law enforcement.
Bingo, you're it.....got you! Out on the water, you can always run, but you can't hide. Where you gonna run to?
Let's see...in Massachusetts, Connecticut, Rhode Island, or New Jersey....first speed violation=loss of your good driver's discount which stays on your record for three years...and costs maybe $500./year in higher insurance. How much is 3 x 500, plus the $88 NH fine?
