• On 27 January 2023, the yacht “La Savina” is at l: 36º 00.0’N and L: 005º 20.0’W on compass course 000º at 7 knots. Magnetic variation is 3º NW and deviation 10º NE. Affected by a current setting S 07º W at 7 knots. Calculate the course and speed made good:
• At dead reckoning position l: 36º 17`N L: 007º 16`W we set course for point P at l: 36º 12`N L: 007º 24`W. Calculate analytically the direct course and distance run.
• At l= 10º 20’N and L= 100º 33’W, sailing on compass course 100º at 10 knots. Calculate the position 1h 48 min later, the total correction being +3º (solve analytically):
