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:
The formulas enable to solve the tasks with a use of electronic calculator and application of traditional methods on plane and sphere, and they also take the Earth’s ellipsoidal shape into consideration. Keywords: loxodrome (rhumb-line sailing), plane (or middle latitude) sailing, Mercator triangle (Mercator sailing) 1. Introduction
Rhumb line calculation: Departure position (latitude, longitude) + Course and Distance, to compute Arrival position; Departure position + Arrival position, to compute Course and Distance; Path of constant course between Departure position and Arrival position. Great Circle calculation

There are four methods of Rhumb-Line Sailing, each one a development of the previous one as the science of Navigation progressed from early days: Parallel Sailing, Plane Sailing, Mid. Lat. Sailing and Mercator Sailing.
19 wrz 2016 · Short Distance Sailing And Rhumb Line Sailing. Posted on September 19, 2016 by Jack Case. In my previous post about the meridian passage long method, I demonstrated how the ‘Short Distance Sailing Formulas’ are used to calculate a vessel’s position at meridian passage.
The rhumb line connecting any two points of the great circle on the same side of the equator is a chord of the curve. Along any intersecting meridian the great circle crosses at a higher latitude than the rhumb line.
