Mercator Sailing Mercator Sailing is another method of Rhumb Line Sailing. It is used to find the course and distance between two positions that are in different latitudes from the large D. Lat. and distance. It is similar to plane sailing, except that plane sailing is used for small distances.
15 paź 2020 · In determining the course and distance between positions using the Mercator sailing method, we make use of two formulae, namely: The following triangles illustrate how these formulae were derived: Angle DAC is the azimuth, side AE is the distance, side AB is the d’lat, side DC is the d’long and side AC is the difference of meridional parts.
10 wrz 2016 · Where the distance exceeds 600 M, it is generally recommended to use Mercator sailing so that results are more accurate results obtained. To get DMP, apply same rule as for D’Lat i.e, same names subtract, different names add. To get distance, use plane sailing formula.
Mercator Sailing. The plain triangle on the right indicates the plot of a Rhumb Line track on a Mercator chart between two points (A and C). By applying simple trigonometry principles the course and distance between the two positions can be determined. The formulae for determining the values are :-
Using two different examples based on Mercator sailing formulae, this video shows how to calculate:a) the course and distance between two geographical positi...
How to calculate Mercator Sailings and gain a greater understanding into why/how they are used as a navigational staple. What are Mercator Sailing Calculations?
Formulas exist which account for oblateness, reducing these errors to less than the length of the typical vessel using them, but far larger errors can be expected on any voyage of more than a few day’s duration. There are two types of Sailings: Great Circle and Rhumb Lines. Both will be described in detail in this chapter.
