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:
Calculation of a distance on loxodrome (rhumb line) and course angle (azimuth) between two points with a given geographical coordinates.
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
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.
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.
6 cze 2019 · The rhumb line, rhumb, or loxodrome is an arc crossing all meridians of longitude at the same angle, that is, a path with constant bearing as measured relative to true or magnetic north. Rhumb lines which cut meridians at oblique angles are loxodromic curves which spiral towards the poles.
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.
