Agreed. They will show the same speed, as long as the radar is used correctly. The NH "headway speed" definition does not indicate if the 6 MPH is relative to the water or the ground, so the law is ambiguous. That said, maintaining 6 MPH over ground against a 3 MPH current would generate a massive wake (9 MPH over water) and I am certain that a ticket would result if caught. I am also confident that the ticket would stand in district court, but might fail on appeal, depends on how the appellate judge interprets the headway speed definition. If I were the judge, I would tie the headway speed definition to the obvious essence of, and reason for, the no wake law and the appeal would fail.
