SAILING
MERCATOR SAILING As we know from the last chapter Mercator projection is a projection of the Earth on a flat plane. Mercator sailing is done on the Mercator chart where the distance between latitudes is not the same and the meridians are parallel lines at equal distance to each other. The Mercator sailing triangle consists…

CHARTS
CHAPTER 3 – CHARTS Advertisements Charts carry a lot of information for navigational use. They represent a portion of the Earth’s surface with a suitable scale on a flat surface. MARCATOR CHART Projection is “Cylindrical Orthomorphic Projection”. Lat*Scale= Long*Scale*sec (lat) Meridional parts – The meridional parts of latitude is the number of longitude units from the…

PARALLEL & PLANE SAILING
As the great circle track crosses the various meridians at different angles the ship has to alter the course throughout the passage. Therefore rhumb line track is used even though the shortest distance between two points on Earth is the shorter arc of the great circle through those points. Rhumb Line – A Rhumb Line or…
