nav, are drinking in sympathy with moron?

consider that that seems likely.

consider also, nav, that moron is crashing towards serious medical
problems
because of his alcohol use.

I bet that you are not as healthy looking as you used to be?

Have you any recent photos?

The effect of tide may be less than that of current...

If you sail due east, north, west and south over the ground with the
same speed over the ground and there were no current, no leeway or
other "disturbing factors", you would still not end up at your
starting point (unless....). In fact on the northern hemisphere you
would end up in a position due west of your starting point.


Well!!! Excuuuse me!

Look, I don't often get points, so I feel that I must defend them.

In most places, the effect of tide would be much greater for a 14 hour
"square" than the curvature of the Earth.

Correct, but useless information for most seafarers.

Would you arrive at your destiantion if you left on a Friday?

Lets say I wanted to visit my girlfriend, and she lives on an
island
just west of my island. There is a lot of reefs in the area so to
stay
clear I calculate a trip-plan that will bring me to her by sailing
14
hours east, 14 hours north, 14 hours west and 14 hours south.
Since
there is no tide and no wind and the water is totally flat, I have
to
use my twin engines (asymmetrical). Every thing goes as planed
and
after 56 hours I arrive at my destination.

Might be greater but not as constant (G)

You're right Buddy, On my first reply I mentioned most of the thing that
would affect DRIFT but I threw in an Etc to not let the Cat out of the
bag.

Let's remember, Bart asked FOR THE NAME of the vector, not what caused
it.
Wally called it Leeway. Not wrong but incomplete. You called it Tidal
Drift (I think) Not wrong but again incomplete

Hey guys, the biggest Navi. Goof in history was made because of the
Global Curve. Chris Columbus thought he was in China because he had no
idea how much larger the Earth was at the equator. His distance for a
degree in nautical miles was half the distance in Europe than at the
middle.

He was just lucky as hell he found land by degrees where he did. He
thought that he had covered the unknown piece of the globe with his
"Chip Log" He assumed the World was round but the unknown was the rest
off the shape. That was still a question mark.

Don-o,

Bet he didn't get Laid when he got there. Friday is a bad luck departure
day an I'm
sure he was looking to get LUCKY (G)

You don't have currents? Here the currents typically run about 1 knot. I
think the gulf stream get up to about 4 knots.

Dave,

"Course made good" ? I was going to agree with you but as I started to
write this post, my mind changed.

Course made good is not the Vector. I guess Course Made Good would
apply. Don't know about the Speed part.

The time for the trip was 56 hrs and 56 hrs was sailed. No more no less.

The End of the trip, after 56 hrs wasn't at the starting position. Now,
was that the trips destination; To sail 4 legs of 14 hrs, 1 East, 1
south, 1 west, and 1 north. Was that the purpose of the Trip? I think
it was.

Now, the course made good created a position. From the question it seems
this was planned, which gave us a difference
(Which was planned for) This created the second point. The two points
were connect with a line, called a vector.

The name of this "Victor" is what was asked for in "the question"

I'm not impressed. I deal with currents up to 10 kts.
