To answer the original question, 1 minute of latitude is approximately 1 nautical mile. It actually varies a bit from exactly one mile. For example, one degree of latitude at the equator is 59.7 nautical miles, while near the pole it is 60.3 nautical miles.

But....1 nm for 1 minute of latitude is close enough!

Longitude, of course, is a different story. It varies from 60.1 nm per degree at the equator to 0.526 nm per degree near the pole. Which is why distance calculations on a nautical chart are always measured off the LATITUDE scale.

I'm out spending more time on my boat than I do in my office . . . but, hang around in here a good part of that time .

We sailed out in the Sound a couple days ago, but conditions were not that pleasant, so pulled into a coastal island harbor for the night . . .

Wish I were sailing.......not only am I in the office at present, but this weekend I cannot take Ragtime out, because we sail on the Mississippi River, and the mouth of our harbor is silted in and the owner of the marina has his dredge upriver working on another harbor!!!!!

Good for you! Where do you keep the boat at? Do you work for Screen Jems?
Just curious...
