• Regarding the local meridian, which answer is correct?
• Local civil time (HcL) is:
• When we find total correction from a transit, the deviation obtained corresponds to:
• The angle between the vessel’s wake and her centreline is:
• On electronic charts, which answer is correct?
• Clutter echoes may swamp a radar screen and hide targets if we set too high:
• On AIS, which answer is correct?
• At ship’s clock 09:00 on 25 March 2023, from 35º 50.0′ N, 006º 10.0′ W we sail on true course 070º at 6 knots. A N wind gives 15º of leeway and a current sets SW at 3 miles an hour. Calculate the dead reckoning position at 10:30.
• On 25 March 2023, at ship’s clock 20:00, we are at 36º 00.0’ N, 006º 10.0′ W. We sail at 8 knots on true course 080º, with a current setting S at 3 miles an hour. Calculate the course the boat will make because of the current.
• At ship’s clock 19:00 on 20 March 2023, we are at 39° 33′ N, 000° 12′ W. We sail at 7 knots: true course 135° for 2 hours, 090° for 4 hours, 075° for 3 hours. From 22:00 on 20 March we enter a current setting SW at 3 miles an hour, constant to the end. Calculate the position at 04:00 on 21 March 2023.
