Navigation A — Coastal — question 53

At 08:00 your vessel is close to the buoy with the characteristics Fl(5)Y.15s (the buoy lies south of Rosh Hakarmel). Under sail only, she must reach the buoy north of Haifa Harbour with the characteristics Fl(2)8s (the buoy carries a radar reflector). The wind is blowing from 045°, and the vessel can sail within 45° of the wind on both tacks. The wind causes 6° of leeway. Her speed is 9 knots. The passage is to be made in two legs (tacks) only, by the shortest route. Find:

  1. The two true courses (TC). 000°, 090°
  2. The two courses over the ground (COG). 354°, 096°
  3. The position at which the vessel will tack onto the second leg. 32°52.2'N 034°55.45'E
  4. The estimated time of arrival at the destination (ETA). 09:00
