• What are the small circles perpendicular to the Earth’s axis called?
• Compass deviation equals the angle between:
• Sailing with wind but no current, what is the angle between the centreline and the boat’s wake called?
• Which nautical publication describes, among other things, the detailed features of the coast and its dangers?
• What is the time a government sets for its territory called?
• In heavy rain or hail, which radar controls should we adjust to filter weather interference and see real echoes better?
• On a GNSS screen, what does WPT mean?
• What happens if we plot a GNSS (WGS84) position on an old paper chart with a different datum, without corrections?
• AIS transmits and receives dynamic and static data on which band?
• At HRB 11:00 when 5 miles SW true of Punta Paloma lighthouse, you set course to pass 5 miles off Cape Trafalgar lighthouse with a NE wind causing 15º leeway (variation 3º NW, deviation +3º). Calculate the compass course Ra:
• At 19:00 ship’s time, 5 miles NW true of Punta Alcázar, you steer compass course Ra = 045º at 8 knots in a current setting South (180º) at 3 knots (variation = 4º NW, deviation = +8º). What is the course made good (Ref)?
• At ship’s clock 08:00 on 21 March 2026, we are at 37° 34.0′ N, 000° 52.0′ E. We sail at 11 knots: true course 240° for 6 hours, true course 180° for 3 hours. Throughout, a current sets southwest (SW) at 3 miles an hour, constant to the end. Calculate the position at 17:00 on 21 March 2026.
