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.

I won't argue that, but at my "preferred" cruising speeds, I burn under
six gph, and I can emulate trawler mileage by running their speeds at
one gph. The latter speeds are perfect for the Potomac River in sections
where there are sights, but I don't think I would enjoy owning a boat
that's no faster than your typical cruising sailboat.

Apparently, knots and meters are tied together, somewhat. A nautical
mile is a minute of latitude. A meter is 1/10,000,000 of the distance
from the equator to the North Pole, and, obviously, a knot is a nautical
mile per hour. Thank you, wikipedia.

They are tied together apparently, but by coincidence, not mathematical
design or part of the Metric system.
Quoting Wikipedia:

Origin
Until the mid-19th century vessel speed at sea was measured using a chip
log. This consisted of a wooden panel, weighted on one edge to float upright
and thus have substantial water resistance, attached by line to a reel. The
chip log was "cast" over the stern of the moving vessel and the line allowed
to pay out. Knots placed at a distance of 47 feet 3 inches (14.4018 m)
passed through a sailor's fingers, while another sailor used a 30 second
sandglass (28 second sandglass is the current accepted timing) to time the
operation.[6] The knot count would be reported and used in the sailing
master's dead reckoning and navigation. This method gives a value for the
knot of 20.25 in/s, or 1.85166 km·h?1. The difference from the modern
definition is less than 0.02%.


[edit] Modern use
Although the unit "knots" does not fit within the primary SI system, its
retention for nautical and aviation use is important for navigational
reasons, since the length of a nautical mile is almost identical to a minute
of latitude. As a result, distance in nautical miles on a navigational chart
can easily be measured by using dividers and the latitude indicators on the
side of the chart.

Nautical speed is sometimes erroneously expressed as "knots per hour" which
would actually be a measure of acceleration, as in "nautical miles per hour
per hour."

The Knot, as I'm sure Harry knows, is a non-SI unit - meaning that it
does not conform to the standards set down by Le Système International
d'Unités or in a real language, International System of Units also
known as the metric system.

The reason is that the Knot is not (get it - knot is not?) is because
it does not directly correlate to the metric or SI system.

Thus, it is not a metric measurement.

And while I'm on my high horse, were you aware that the meter is based
on the distance traveled by light in 1/299,792,458 of a second? And
that this measurement is 1/10,000,000 of the distance from the Equator
to the North Pole on a line running through Paris? PARIS!!

How stupid is that? No wonder the metric system is so weird. Paris -
honest to pete. Damn Frenchies never got over the English having the
Prime Meridian run through Greenwich. :)

He never stated that it was. According to Wikapedia the definition of a knot

calculate same.

I've known a few European sailors. They measure wind speed in both
knots and meters/second depending on what wind instruments the boat
has. It turns out that knots are very closely approximated by
doubling meters/sec.

Meters and yards are absolutely tied together, by law. Exactly
25.4mm/inch. Not to mention that the meter is not defined in terms of
the size of the earth, as originally. You did say somewhat, which is
true.
