What is transverse sailing?

What is the purpose of Traverse sailing?

Also found in: Encyclopedia. (Naut.) a sailing by compound courses; the method or process of finding the resulting course and distance from a series of different shorter courses and distances actually passed over by a ship.

What are the different sailing methods?

The most common navigation methods are satnav, dead reckoning, and radar navigation. Every method has advantages and disadvantages. For example, dead reckoning and radar can be used to determine your location based on just one point or object.

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.

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 Composite great circle sailing?

A method of sailing along the shortest route possible without crossing poleward of a specified latitude. … This comprises two great circle routes, the first starting at the place of departure with its vertex on a limiting parallel of latitude.

What is the difference between plane sailing and Mercator sailing?

Plane sailing is not intended for distances of more than a few hundred miles. … Mercator sailing provides a mathematical solution of the plot as made on a Mercator chart. It is similar to plane sailing, but uses meridional difference and difference of longitude in place of difference of latitude and departure.

Why is it called plane sailing?

In the past, in order to determine distance, calculations were made based on the assumption that the earth was flat and not spherical. To make calculations simple, sailors assumed that the ship was sailing on a flat or a ‘plane surface‘. The original expression was, in fact, ‘plane sailing’.

What is the limit distance for a plane sailing method?

When we refer to plane sailing we mean sailing from one position to another where the latitude and longitude of each is different to the other. Because we are using a mean latitude, this method is not very accurate over long distances and should be confined to distances of 600 nautical miles or less.

Why was plain sailing in the end?

The expression is mostly used in informal contexts to mean ‘smooth and easy progress’. When you say that something was plain sailing, you mean things went off without a hitch; there were no problems or obstructions of any kind along the way.

What is the meaning of 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 distance between two meridians?

Measuring the Distance Between Meridians of Longitude Along a Parallel of Latitude. At the Equator, the distance between meridians of longitude is 60 n.m. (or 60.113 to be precise). However, as we move north or south equator, we find that the distance between them decreases as they converge towards the poles.
