• Which parallel has a latitude of about 23° 27′ S?
• Which equipment works because some electromagnetic waves reflect off objects and return to their source?
• On a radar we can find the bearing or relative bearing of an echo with:
• Official ENCs of the Spanish coast are produced by:
• At HRB 15h 00m you simultaneously obtain Dv Punta Paloma = 340º and Dv Punta Cires = 120º, then head for Tangier port breakwater light with an East wind causing 20º leeway (variation 4º NE, deviation –4º). Find Ra:
• At HRB 12h 12m when due South true of Punta Europa and due East true of Punta Carnero, you head for Ceuta green entrance light at 6 knots in a SW current of Ihc = 2 knots (variation 3º NE, deviation –9º). Find Ra and arrival HRB:
• At 11h 00m in position 36º 15.0' N, 005º 15.0' W you steer compass course 173º with a West wind causing 15º leeway (variation 3º NE, deviation +8º). Calculate your position when Punta Europa lighthouse is abeam:
• At HRB 10h 20m in position 35º 55.0' N, 005º 50.0' W you head for Barbate landfall light in a current setting Rc = 110º at Ihc = 2 knots (variation 1.5º NE, deviation –11.5º) to arrive at HRB 13h 08m. Find Ra and Vb:
• At ship’s clock 09h 00m on 1 June 2025, we are at 15° 10.0′ N, 179° 22.0′ E. We sail at 10 knots: true course 135° for 4 hours, true course 090° for 3 hours. Throughout, a current sets SE at 3 miles an hour, constant to the end. Calculate the position at 16h 00m on 1 June 2025.
