## What is Mercator sailing method?

[mər′kād·ər ‚sāl·iŋ] (navigation) **A method of solving the various problems involving course, distance, difference of latitude, difference of longitude, and departure** by considering them in the relation in which they are plotted on a Mercator chart.

**The most common navigation methods are satnav, dead reckoning, and radar navigation.**

- Dead reckoning.
- Pilotage.
- Celestial navigation.
- Inertial navigation.
- Radio navigation.
- Radar navigation.
- Satellite navigation.

## What is a Mercator chart how was it made?

Mer·ca·tor projection

(mər-kā′tər) A **method of making a flat map of the Earth’s surface so that the meridians and parallels appear as straight lines** that cross at right angles. In a Mercator projection, the areas farther from the equator appear larger, making the polar regions greatly distorted.

## What are meridional parts?

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

## What is the importance of using Mercator sailing in calculating for course and distance?

Charts used on board ships generally are Mercator charts. On these charts bearings, courses and distances can be directly read off or plotted on the charts. For calculating course and distance between two given points on surface of the earth, the Mercator sailing formula is **more accurate than plane sailing formula**.

## What is the difference between plane sailing and Mercator sailing?

* It is **similar to plane sailing** except that plane sailing is used for small distance. * In mercator sailing the d’lat is expressed in longitudinal units, which is the difference of meridianal parts. * In plane sailing the d’long is expressed in latitude units or Nautical miles.
