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???

Most Americans can't even learn English, so to expect them to learn the
metric system is more than a stretch.

I don't think there is anything metric about knots. Metric would be
km.
