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.

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.

What are the types of sailing in navigation?

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.

How many types of sailings are there?

There are two types of sailing: cruising and racing (scrolls down).

Why is Mercator sailing important?

Mercator sailing is used to calculate the position after sailing along a rhumb line other than in a North-South or East-West direction. It is also used to find course and distance between two known positions.

What is a Mercator chart how was it made?

Mercator projection

A cylindrical map projection in which the meridians and parallels appear as lines crossing at right angles and in which areas appear greater farther from the equator. Straight line segments represent true bearings, thus making this projection useful for navigation.

What are meridional parts?

Definition of meridional part

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

How is DLo calculated?

The formula for the DLo technique is: tan Lx = (cos DLovx) (tan Lv). 2. Select equal distances from the vertex and solve for corresponding positions along the great circle route.

What is plane sailing in navigation?

Definition of plane sailing

1 : the navigation or conducting of a ship by neglecting the earth’s curvature and considering the earth or a part of it as a plane.

What are 3 types of navigation?

Three main types of navigation are celestial, GPS, and map and compass. In order to better understand why we teach map and compass at High Trails, it is helpful to learn the basics of all three techniques.

What is navigation and its types?

The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation. It is also the term of art used for the specialized knowledge used by navigators to perform navigation tasks.

How does Mercator chart measure distance?

On a Mercator chart, the latitude scale on the sides of the chart serves as the distance scale. It’s worth remembering that only the vertical, latitude scale on a Mercator chart can be used to measure distance, not the horizontal longitude scale.

What Sailing method is used to find course and distance between two positions which are not in the same latitude and when the distance is small?


Plane sailing is a method of solving relationship between distance, d′lat, departure and course when a ship sails along a Rhumb other than along parallel of latitude or meridian.

Which types of Sailing maintain constant true direction?

The principal advantage of a rhumb line is that it maintains constant true direction. A ship following the rhumb line between two places does not change its true course. A rhumb line makes the same angle with all meridians it crosses and appears as a straight line on a Mercator chart.
