• If we find total correction from a transit, the deviation obtained is valid for:
• The quality of echoes on the radar screen can be affected by:
• On GNSS equipment, course made good is shown by the acronym:
• What information can a GNSS installation give us?
• Which kinds of electronic chart are specially designed for marine navigation?
• In position 36º 00.0' N, 005º 40.0' W you set course to pass 5 miles off Cape Trafalgar lighthouse with a NE wind causing 12º leeway (variation 4º W, deviation –6º). Calculate the compass course Ra:
• At ship’s clock 06:00 we are at 35º 50.0′ N, 005º 50.0′ W, on compass course 350º. A westerly wind gives 20º of leeway. Calculate the course made by the boat under the wind, given magnetic variation = 5º NE and compass deviation = +10º (plus).
• At ship’s clock 18:15 we are at 36º 05.0´ N, 006º 10.0´W. We sail at 6 knots on true course 160º, with an easterly wind giving 10º of leeway and a current setting SW at 3 miles an hour. Calculate the dead reckoning position at 20:45.
• 04:10 3.05 18 10:08 0.77 18 16:23 2.99 18 22:24 0.81 18. Calculate the official time between the first high water and the first low water of 18 March 2025 at which we will have a sounding of 3.95 metres on a shoal charted at 1.63 metres. Clock advance: +1 hour.
• A ship at 26º 40' S, 177º 35' E wants to sail to 05º 15' S, 179º 28' W. Calculate the direct course (to the nearest half degree).
