Mercator Sailing Revision

Calculate the DR Position of the ship with the following information:

Initial Position: N 10° 15’, E 177° 30’

True Course: 135°(T)

Distance Steamed: 941 miles

Calculate the True Course and Distance from:

Position A: S 10° 15’, E 179° 30’ to Position B: N 35° 45’, W 169° 15’

Calculate the DR Position of the ship with the following information:

Initial Position: N 50° 33’, W 007° 25’

True Course: 237°(T)

Distance Steamed: 1008 miles

Calculate the True Course and Distance from:

Position A: S 51° 16’, W 061° 10’ to Position B: N 010° 16’, W 018° 09’

A vessel is expected to sail on a Rhumb Line track from:

Cape Town, South Africa (S 33° 54’, E 018° 25’) to Port Stanley, Falkland Island ( S 51° 42’, W 057° 50’). If the vessel sails at 9pm on 07 February 2019 and steams at an average speed of 15 knots, calculate the ETA of the vessel (Local Standard Time).

Cape Town, South Africa: +2 UTC

Port Stanley, Falkland Island: -4 UTC

A vessel travels from Position ‘A’: 02° 10’S, 002° 20’W to Position ‘B’: 05° 20’N, 003° 35’E.

Using Mercator Sailing, find:

(a) The longitude where the rhumb line track crosses the Equator.

(b) The latitude where the rhumb line track crosses the Prime Meridian.
