Knots being phased out?
Hi,
I have been told that all new equipment, chartplotters, speedometers and
the like will not have knots as a speed option.
Knots will be phased out and KPH will be the new standard for marine
equipment. Has anybody heard of this? If so where? Some links please if available. Thanks

| What? Longitude doesn't vary with latitude??????
Are you also saying that Latitude DOES vary with regards to
longitude?????? |

| For Vulcan measurments check out these great Vuls ! The BB team is a
bit rough but gotta love the VB team!!!!! At least I do. http://vulcans.uhh.hawaii.edu/ Also be advised that Ferengi Rule of Acquisition No. 6 requires:
Every vessel shall at all times proceed at a safe speed measured in KPH
so that she can take proper and effective action to acquire, take, or
possess anything of value appropriate to the prevailing circumstances
and conditions. |

Of course, that scale we measure on the left & right sides of the chart
are the latitude scales. |

Hmmmmm..... I think you have your terms "Wrapped around the Axle"
here.... Nautical Miles is based on "Minute of Latitude" which does
NOT change since the distance from the Equater to the Poles is ALWAYS
the SAME, from any place on the EQUATER. Therefor, when dividing that
distance in Degrees, MInutes, and Seconds, will ALWAYS produce the same
Unit Lengths. Where as Longitude is the cicumfrence of the earth at
the equater divided into Degrees, Minutes, and Seconds, and that DOES
change Unit length as you move closer to the Poles. Longitude is marked
on the bottom and top of Maps, where Latitude is marked on the right and
left had edges of Maps. One ALWAYS uses the Latitude markings for
distance because they do NOT change Unit Length, EVER..... Bruce in alaska |

| Since the earth is not a perfect sphere, the length of a minute of
latitude _does_ vary slightly with latitude - Bowditch has a table
showing the lengths of a minute of Lat and Long for various latitudes.
I vaguely recall a minute of latitude varies by 300 ft or so from
equator to pole (don't recall which end is longer), and is only a
nautical mile at about 44 degrees. |

| When I was young (about 12) , I often hung around a service station owned
by a friend of my father. One day an elderly guy pulled in driving an old
Rambler station wagon. His muffler and exhaust system from the engine back
was dragging on the ground. To get him by until he could get the car in for
a permanent repair, the station owner handed me some bailing wire and told
me to climb under the car and wire the exhaust back up as a temporary fix. It was temporary alright. I did a great job carefully wiring the exhaust
pipe tightly around the driveshaft. Eisboch |

| Isn't KPS "Knots per Hour" = "Knots"? This sounds exceedingly unlikely. It isn't just boating but the entire
aviation world that would have to convert if the nautical mile was
abandoned. |

| Since the nautical mile is defined as one minute of latitude, I doubt it
will ever disappear in earth based navigation. Roger Long wrote: |

| This is true. USCG is reporting that the term and nautical application
of "knot" will be replaced in 2014 by Grek-Gohk!, which is the Klingon
unit equal to .987, .878, and .799 miles depending on sea conditions. Cheers, Robert B

| I can see it now: A CA or EUR boat shopper looks at a runabout. Shopper: One little thing that bothers me is that the speedometer reads
in kph, rather than knots. Is there an option to get a speedometer that
reads in knots? Unprofessional salesperson: Oh no. Of course not. Didn't you know that
all new navigation equipment will eliminate knots as a unit of
measurement and the new worldwide standard will be kph? **** Sometimes a depth sounder is appropriate in the showroom, where it has
been known to get piled up pretty deep indeed. :-) |

| The Nautical Mile was originally based on a minute of latitude, but
the length of a minute of latitude varies with latitude, so an
International Nautical Mile is now defined as 1852 metres exactly, or
6076.11549 US feet, approximately, according to Bowditch. |
Peter

| I believe that the nautical mile is based on the minute of LONGITUDE not
latitude. Longitude doesn't vary with changes in latitude (or attitude).
That's why when you are using paper charts (remember those) you measure
the distance with your dividers on the longitude scale on the east or
west side of the chart.
