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:
Formulas for distances along rhumb-line tracks, which take the Earth’s oblateness into account, are available [5], and tables for latitude, longitude, and distance along a rhumb line on the...
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
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 sailing takes advantage of the shorter distance along the great circle between two points, rather than the longer rhumb line.
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.

Suitable positions are determined along the great-circle track and rhumb lines between these positions are calculated. The consecutive rhumb lines will approximate to the great-circle track. Composite sailing, as its name implies, involves the use of a composite track.
