Question 1 of 27070

Q

The wind speed and direction observed from a moving vessel is known as __________.

🔍 Key Concepts

• Relative vs. true motion of wind and vessel • How wind feels/appears to someone on a moving vessel vs. measured at a fixed point • Difference between true wind and what is experienced onboard when underway

💭 Think About

• Ask yourself: When you are standing still on a dock, is the wind you feel the same as when the vessel is moving ahead at speed in calm air? What changes? • Think: Which term describes the combination of the real wind and the vessels own motion through the air? • Consider which option names a concept of wind versus which options name an instrument or something that doesnt normally describe wind at sea.

✅ Before You Answer

• Does the correct term describe wind as experienced from the moving vessel, not from a fixed reference? • Eliminate any choice that refers to an instrument rather than a type of wind. • Make sure the term you pick is commonly used in sail trim, course to steer, and leeway calculations.
