🔍 Key Concepts

• Difference between true wind and apparent wind • Effect of a vessel’s own speed and heading on how the wind is felt and measured on board • What a wind vane actually measures (relative to the vessel or to the earth?)

💭 Think About

• If the vessel is stopped, what does the wind vane show? Now what changes when the vessel starts moving ahead? • Is the instrument mounted on the vessel giving you wind relative to the moving ship, or corrected for the ship’s motion over the ground? • Which term describes wind as experienced on deck versus wind corrected for the vessel’s motion?

✅ Before You Answer

• Make sure you know the definition of apparent wind versus true wind • Think about whether a simple wind vane has any way to measure the vessel’s speed to compute true wind • Ask: Is the reading from the vane relative to the ship’s heading or to a fixed north reference?
