Short distance sailing is a term which is applied to sailing along a rhumb-line for distances less than 600 nautical miles. From the formulas derived above, the following are used extensively in short distance sailing:

Rhumb Line. It may be difficult to believe that if you sail on a constant course, except on exact East or exact West, you will end up at the North or the South pole, assuming there is no land in between. The constant course track that appears like a spiral on the Earth spheriod is called a Rhumb Line track. Mercator Sailing.
Calculation of a distance on loxodrome (rhumb line) and course angle (azimuth) between two points with a given geographical coordinates.
The rhumb line and great circle may intersect each other, and if the points are equal distances on each side of the equator, the intersection takes place at the equator.
Great Circle calculation. Computes the shortest path between Departure position and Arrival position. Celestial navigation course for beginners. Voyage planning/passage planning tool. Single rhumb line and great circle calculations on an ellipsoid.
comparing the Great Circle and the Rhumb Line tracks between place of departure at 6000N 01000E and different destinations, all of which are located on the 6000N parallel. In this case the Rhumb Line track will be 270°, and the Rhumb Line distance is easy to calculate, using the formula for departure. Observing the Great Circle track and
