• Regarding local civil time (HcL):
• Meridians:
• Which statement is correct?
• The compass course is:
• Updates to official charts, to include new dangers, are made through:
• Official ENCs (Electronic Navigational Charts) are:
• AIS is used to:
• Steaming on true course 332º at 8 knots, you cross the opposition line of Punta Almina and Punta Europa lighthouses and observe Punta Europa lighthouse at compass bearing Da = 338º. Calculate the total compass error:
• On 25 July 2020 when due South true of Punta Paloma lighthouse and SW true of Isla de Tarifa lighthouse, you head to pass 3 miles off Punta Cires at 6 knots with a NW wind (15º leeway), chart dm 5.5º E 2015 (6' W) and dev +6º. Find Ra:
• At ship’s clock 16:00 we are at 36º 04.0′ N, 006º 00.0′ W. We sail at 6 knots on compass course 240º. There is a current setting NW at 3 miles an hour and a SE wind giving 10º of leeway. Variation = 3º NW and deviation = +8º (plus). Calculate the dead reckoning position at 18:00.
• At HRB 15:00 when due South true of Punta Camarinal and due West true of Punta Paloma, you head for Tangier breakwater light in a West current of Ihc = 3 knots (dm 3º NE, dev –3º) to arrive at HRB 18:00. Find Ra and Vb:
• A ship at 15º 00.0′ N, 179º 15.0′ E sails at 10 knots: Course 120º for 3 hours. Course E (east) for 4 hours. Course 150º for 6 hours. Calculate the arrival position.
