Knots (nautical miles) are used in locations where navigation is regularly measured in nautical miles. (One nm = one MINUTE of latitude). Aircraft and sailboats -- particularly offshore cruising sailboats -- use knots.

Headway speed is expressed in MPH, as most boaters hop out of their automobiles and into their Winnipesaukee powerboats. Using 6MPH is probably a corruption of a 5 knot speed limit.
