This video explains the procedure of calculating the true or apparent wind direction and speed by incorporating the ship's course and speed. The direction and speed of the wind is determined by using the OAT triangle, where: AT stands for the ship's course and speed; OA is the direction and speed of the apparent wind; and OT is the direction and speed of the true wind. This is example 2 in the determination of wind direction and speed. Link to example 1 is provided: • Calculating the direction and speed of the...
