• The COG function refers to:
• The time difference between two places is:
• Radar range depends, among other things, on:
• The Arctic Circle:
• The angle between the wake left by the boat and her fore-and-aft line is called:
• When the Sun, Earth and Moon are in a straight line, we get:
• Information to update the magnetic variation is found:
• To set legal time, the Earth was divided into:
• At HRB 17-00 in true position l = 36º-07.0' N, L = 005º-57.4' W you head for Cape Spartel lighthouse at Vhb = 7 knots; at HRB 19-00 you take Dv Punta Malabata = 138º and Dv Cape Spartel = 210º. Calculate Rc and Ihc:
• At 20:00 ship’s time you take a compass bearing of Punta Malabata lighthouse Da = 190º while observing Polaris at compass azimuth Za = 355º (assumed at the Pole). What is the true bearing (Dv) of Punta Malabata?
• At HRB 21-45 on the Isla Tarifa–Punta Alcázar opposition at 5 miles from Punta Alcázar, you steer Rv = 070º at Vhb = 6 knots in a current setting Rc = 095º at Ihc = 3 knots. Find your distance off Punta Europa when crossing the Punta Europa–Punta Almina opposition:
• At l = 35º-40.0’ N, L = 005º-32.0’ W we head for a point at l = 36º-05.0´ N, L = 004º-44.0’ W. Calculate the distance between the two points.
• At l = 35º-50.0’ N, L = 006º-10.0’ W, we set course for a point at l = 34º-33.0´N, L = 009º-23.0’ W, speed 7 knots, with a current setting 090º at 3 knots. Calculate the course made good.
• Approaching the Strait making good surface course Rs = 070º with a SW wind causing 6º of leeway, you take a relative radar bearing of Cape Spartel = 45º (starboard). What is the true bearing (Dv) of Cape Spartel?
