When rotating to move in a forward direction, which component draws its supply of water from every direction forward of and around the blades?

When rotating to move in a forward direction, which component draws its supply of water from every direction forward of and around the blades?

• A. RUDDER
• B. KEEL
• C. PROPELLER
• D. HULL

Answer: (C)

Rotating the propeller creates a suction that pulls water in from ahead of and around the blades. As the blades push water rearward to generate thrust, water is drawn from the forward direction and from around the circumference of the propeller disk, supplying the flow the blades act on to move the boat forward. The rudder, keel, and hull affect steering, stability, and resistance, but none of them provide the water flow directly into the blades.
