Tonight was a beautiful night. Full moon. High tide. Just perfect. Dumped off the Wife and kids after some fun tubing. Then went for a solo ride so I didn't have to hear "Slow down". (Which I hear often).

Here's what happened....

I was reading 71.4 kn on my garmin 182C unit and I wanted to campare it to the gps speedo to see if there was a discrepency. I would say that they're pretty damn close.

71.4 x 1.15 = 82.11


Here's some useless information that I found. Just thought I would share it.

You may have wondered where the units of knots came from. A knot is exactly equal to 1/60th of a degree of latitude. A 1/60th of a degree of latitude is known as a minute of latitude. Therefore a knot is equal to one minute of distance. There are 90 degrees from the equator to the pole. Therefore a knot is 1/5,400th the distance from the equator to the pole. This number is found by multiplying 90 (degrees from equator to pole) × 60 (number of minutes in a degree of latitude). At sea, one's position is always based on degrees, minutes and seconds, so therefore how fast you traverse the ocean is based on "minutes" traveled per unit time (hour); hence, the nautical mile per hour or knot. In centuries past, mariners determined the speed of their ships using a knotted "log line." The buoyant line was let out freely as the ship sailed along, and then the number of knots let out during a given time gave the shipmaster a measure of his vessel's speed.

A knot is related to meters per second much more closely than miles per hour is. A knot is very close to 0.5 meters per second!! Therefore, the table below is much closer to accurate than the table above. If a value on an analysis chart is given in knots, simply divide this by 2 to get the wind speed in meters per second. Most weather charts will report wind speed using the units of knots.

10 knots × 1.15= 11.5 mph × 0.45 = 5 m/s
20 knots × 1.15 = 23.0 mph × 0.45 = 10 m/s
30 knots × 1.15 = 34.5 mph × 0.45 = 15 m/s
40 knots × 1.15 = 46.0 mph × 0.45 = 20 m/s



Thank god for modern technology.

Ray,
Congratulations on the increased speed #s. Did the gear change affect your acelleration?
Regards,
Steve

Hi Steve


Yes it did but not dramatically. I feel that the new set-up is more sensitive to trim and tab input. (In a good way). I will say though that the other set-up was more consistant with load/performance. With the 1.50 set-up it would run the same speed with a full load of fuel and 5 people or just me and less fuel. It seems that if I have a substaintial amount of fuel and a few fat azz's aboard, the performance drops off a bit with the new set-up. That's OK because Not everyone feels comfy doing 80 and not being at the wheel. If I want to go fast I just tell everyone to GET OUT!
