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 between two places does not change its true course. A rhumb line makes the same angle with all meridians it crosses and appears as a straight line on a Mercator chart. For any other case, the difference between the rhumb line and the great circle connecting two points increases (1) as the latitude increases, (2) as the difference
composite sailing. 1204. Rhumb Lines A rhumb line makes the same angle with all meridians it crosses and appears as a straight line on a Mercator chart. The principal advantage of a rhumb line is that it maintains 1. latitude.
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.

for x = 1,2 The point of departure and the destination are used successively as point X. Solve the two great circles at each end of the limiting parallel, and use parallel sailing along the limiting parallel. Bowditch 2019 - 1213.

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 the rhumb line track between the same positions on the Earth’s surface: • The Great Circle track will continuously change it’s true direction, while the 4 The Rhumb Line and
