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"
