Navigation A — Coastal — question 25

At 15:30 your vessel is at 31°57'N 034°20'E. From this position she must reach the entrance of Ashdod harbour under sail. The wind is from 100° and causes 5° of leeway. She can sail within 40° of the wind on either tack. Make the passage as close-hauled as possible, in two legs (tacks) only. Find:

  1. The two true courses (TC). 140°, 060°
  2. The two courses over the ground (COG). 145°, 055°
  3. The total distance sailed. 23 miles
