Q

As a ship moves through the water, it drags with it a body of water called the wake. Which term defines the ratio of the wake speed to the ship's speed?

🔍 Key Concepts

• Ship wake and how water moves with the hull • The idea of a ratio between two speeds (wake speed and ship speed) • Basic propeller/hull interaction terminology from naval architecture

💭 Think About

• Which option name sounds like a dimensionless ratio comparing two speeds, rather than an absolute speed or a path distance? • Does the term describe a property of the water flow around the hull, or something about the ship’s track over the ground? • Which terms are commonly used in propeller design and hull–propeller interaction, specifically related to how the hull affects inflow to the propeller?

✅ Before You Answer

• Identify which choice refers to a ratio (not a distance, not a single speed, not a path over ground). • Eliminate any term that clearly relates to navigation/track instead of hull–water flow. • Verify which term is used in propeller theory to describe the effect of the ship’s wake on inflow speed to the propeller.
