Why Parallel sailing is significant?

What is meant by 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 are the characteristics of parallel sailing?

Parallel Sailing

Parallel sailing means sailing along a parallel of latitude which also means maintaining a true course of east 090 or west 270. The distance sailed would be the departure at that latitude.

What is the significance of middle latitude sailing?

A method of converting departure into difference of longitude, or vice versa, when the true course is not 090° or 270° by assuming that such a course is steered at the middle latitude.

What is the use of parallel sailing in navigation?

Parallel sailing is the interconversion of departure and difference of longitude when a vessel is proceeding due east or due west. 4. Middle- (or mid-) latitude sailing uses the mean latitude for converting departure to difference of longitude when the course is not due east or due west.

What are the two categories of Mercator sailing?

In broad terms, there are two main types of sailing, namely, the Rhumb Line sailing and the Great Circle sailing.

When planning to cross an ocean is it always best to use great circle sailing?

Great Circle Sailing is used for long ocean passages. For this purpose, the earth is considered a perfect spherical shape; therefore, the shortest distance between two points on its surface is the arc of the great circle containing two points.

What is Traverse 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.
