Q

What is TRUE concerning an anemometer on a moving vessel?

🔍 Key Concepts

• Difference between true wind and apparent wind on a moving vessel • What an anemometer actually senses at its location on the ship • Effect of the vessel's own speed and heading on the wind you feel on deck

💭 Think About

• If the ship were stopped in the water, what type of wind would an anemometer read? Now, what changes when the ship starts moving? • Think about standing on the bow of a fast-moving boat on a calm day: do you feel any wind? What kind, and what created it? • Does an anemometer have any built‑in way to know the ship’s motion through the water so it can correct its reading?

✅ Before You Answer

• Be clear on the difference between true wind (wind over the Earth’s surface) and apparent wind (true wind combined with vessel motion). • Ask whether a basic anemometer on board is automatically corrected for the vessel’s speed and heading, or if it just measures local wind at that point. • Check which options mention apparent vs true and consider what the instrument can and cannot determine by itself.
