Hello all,

why are recreational boatspeed in the US measured in MPH when the rest of
the world including the US proffesional mariners uses knots???

In aviation we've gone back and forth. The real argument for MPH in
aviation is that its faster and looks better on marketing flyers. Not
sure if that is the reason in boating or if its just that most people
have no idea what a knot is.
