What are types of Sailing for Navigation of ships?

PLANE SAILING: DEPARTURE = (D’LONG X COS M LAT DEP)plane sailing
Parallel sailing is the interconversion of departure and difference of longitude when a vessel is proceeding due east or due west.
PARALLEL SAILING: DEPARTURE =(D’LONG X COS LAT D’ LONG)
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.Mercator sailing
Find course & Distance:

TAN CO = (D’LONG /DMP D’LAT)

DIST. = (D’LAT / COS CO)

Find Arrival Postion:

D’LAT = (DIST X COS CO)

D’LONG = (TAN CO X DMP)
