Navigation A — Coastal — question 18

Your vessel is a sailing yacht, and at 16:00 she is at 32°20'N 034°20'E. The wind in the area is due east and causes 5° of leeway. She can sail within 40° of the wind on either tack. She must reach Herzliya Marina at 23:00. Make the passage as close-hauled as she can sail, on two tacks only. Find:

  1. The two true courses (TC). 130°, 050°
  2. The two courses over the ground (COG). 135°, 045°
  3. What is the distance sailed? 33.2 miles
  4. What speed is needed to reach Herzliya Marina on time? 4.7 knots
