What is the use of parallel sailing?

What is parallel sailing?

: spherical sailing in which the course is along a parallel and departure is the product of cosine latitude times the difference of longitude —opposed to meridian sailing.

What is the difference between parallel sailing and plane sailing?

Whenever ship sails on a east or west course, it is called parallel sailing. The distance travelled on this course along parallel of latitude is equal to departure. When ship sails along a rhumb line, it is called plane sailing. Rhumb line is a line on surface of earth which cut all meridians at same angle.

What is the purpose and advantage of using composite sailing?

Composite sailing (see Article 2402 Page 2 346 THE SAILINGS and Article 2410) may save time and distance over the rhumb line track without leading the vessel into danger.

Why do we use Mercator sailing?

* Mercator sailing is another method of Rhumb line sailing . * It is used to find the course and distance between two position that are in different latitude from the large d’lat and distance.

What are meridional parts?

: the linear length of one minute of longitude on a Mercator chart.

What is transverse sailing?

: plane sailing in which a ship follows two or more courses in succession with the difference in latitude and departure being added algebraically to find a single resultant course and distance.

What is Meridian sailing?

: sailing north or south —opposed to parallel sailing.

What is composite sailing?

: a combination of great circle and parallel sailing in navigation.

What is the advantage of using great circle sailing?

The advantage of a great circle is obvious, the shorter distance. The disadvantages, depending on latitude, could be quite a few. Colder weather, stronger winds, higher seas and perhaps even icebergs.

What is a rhumb line used for?

A Rhumb Line (also known as a loxodrome) is a line on the earth’s surface that crosses all meridians at the same angle. It is used as the standard method of plotting a ship’s course on a chart.
