• How far is the Arctic Circle from the North Pole?
• Parallels:
• The action of the wind on the sides and superstructure makes the boat:
• Sailing with the radar head-up:
• Notices to mariners are used to:
• The system used by today’s satellites is:
• With wind and current, relative bearings are taken with respect to:
• In position l = 35º 46.0' N, L = 006º 19.0' W you set course to pass 3 miles off Cape Spartel lighthouse with a NW wind causing 6º leeway once on course. Calculate the true course Rv:
• At HRB 11-30 on Ra = 086º at Vhb = 6 knots (deviation 3º NW, variation 3º NW), you take Da Punta Alcázar = 136º; at HRB 12-00 you take Da Punta Alcázar = 176º. Calculate your position at HRB 12-00:
• At l= 35º-59.0´N L= 006º-15.0´W there is a current setting E at 3 knots, compass course 070º, speed 6 knots. Deviation= 5 NE, variation= 3 NW. Calculate the course and speed made good.
• At l= 36º-00.0´ N L= 006º-20.0´ W, speed 6 knots. At ship’s clock 19-00 we sail on true course 290º. At 23-00 we change to true course 260º until 04-00. Throughout, a current sets 080º at 4 knots. Calculate the position at 04-00.
• At HRB 20-00 while on the opposition line between Punta Europa and Punta Almina, you take a compass bearing of Punta Europa Da = 338º. Find the total compass error:
