# Is Sail Sailing or plane sailing?

## 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 was the 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 formula for plane sailing?

This plane triangle is essentially an artifice which shows the trigonometrical relationships between the arguments involved. These relationships are now known as the plane sailing formulae, namely: departure = distance x sine course d. lat. =distance xcosine course.

## 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 advantage and disadvantages of 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 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.

• Pilotage.

## What is short distance sailing?

Short distance sailing is a term which is applied to sailing along a rhumb-line for distances less than 600 nautical miles.

## Is not all plain sailing?

If you say that a task was not all plain sailing, you mean that it was not very easy. Pregnancy wasn’t all plain sailing and once again there were problems.

## 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 the rhumb line in sailing?

Loxodrome, also called Rhumb Line, or Spherical Helix, curve cutting the meridians of a sphere at a constant nonright angle. Thus, it may be seen as the path of a ship sailing always oblique to the meridian and directed always to the same point of the compass.
