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 is Mercator sailing and where it is most applicable?
Sailing is the term used in the maritime world to describe the method used to solve the problem of course and distance between two positions. … The Mercator Sailing is the most accurate method employed in marine navigation to handle calculations related to Rhumb Line sailing.
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.
There are different methods of locating your position, different plotting methods, and also different ways to determine your course. The system of locating, plotting, and setting a course is called a navigation method. The most common navigation methods are satnav, dead reckoning, and radar navigation.
What is 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.
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 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 are the types of sailing?

- – Cruising.
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.
What is the formula to obtain the distance in Mercator sailing?
DISTANCE = (D’LAT × SEC CO.)
What is difference of latitude?
Dictionary of Nautical Terms
difference of latitude. The distance between any two places on the same meridian, or the difference between the parallels of latitude of any two places expressed in miles of the equator.
