• The great circles perpendicular to the parallels:
• The angle between the true course and the water track the boat makes is called:
• When a vessel is at latitude 23º 27′ S:
• Which expression is correct?
• If we work out a total correction on a given heading:
• Regarding GNSS, which statement is correct?
• Drift (“deriva”) is defined as:
• At ship’s clock 09:00 at latitude 35 50´N and longitude 006º 10´W we sail on compass course 060º at 6 knots with a NW wind giving 10º of leeway. Variation = 5º NE. Deviation +4º (plus). Calculate the position at 10:30.
• At HRB 14:00, 5 miles due North true of Punta Malabata lighthouse at 5 knots, you head to pass 2 miles off Punta Cires with a North wind causing 15º leeway (variation 4º NW, deviation +12º). Calculate the compass course Ra:
• At HRB 15:00 steering Rv = 075º at 7 knots you cross due North true of Cape Spartel lighthouse, and at HRB 16:00 you take true bearing Dv Punta Malabata = 160º. Calculate your position at HRB 16:00:
• A ship at 13º N, 176º 30.0´E wants to sail to 11º S, 174º 50.0´E. Calculate the direct course (to the nearest half degree) and distance.
