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 results of this study show that the proposed formulas are simpler, shorter and more than twice as fast as other geodetic methods of the same accuracy, used for sailing calculations on the ellipsoid, such as “rhumb-line sailing” and “great elliptic sailing”.
Formulas regarding the rhumbline sailing computation are given in a form convenient for calculations done with a use of commonly accessible electronic calculators.

Introduction. The formulas for determining a ship's dead-reckoned position, given an initial known location, the vessel's course and speed, and the time elapsed, are referred to as the sailing...
27 cze 2024 · A student of navigation who refers to the standard textbooks will be confronted with a multiplicity of sailings which are said to include plane sailing, parallel sailing, middle or mid-latitude sailing, mean latitude sailing, traverse sailing, short distance sailing using rhumb-line formulae, mercator sailing, great-circle sailing, approximate ...
1 cze 1995 · This paper provides simple formulas that include the earth's oblateness, which can be readily applied to sailing calculations. The accuracy of these formulas is assessed, and they are shown to be good to about 10 m over ranges up to 1000 km.
