🔍 Key Concepts

• Different propeller configurations used for special maneuvers (tugboats, ferries, thrusters) • How blade orientation and motion differ between normal screw propellers and more advanced designs • Which types of propellers allow rapid changes in thrust direction without changing shaft rotation

💭 Think About

• Think about which option describes a propeller whose blades move in a circular path under the hull, rather than a simple spinning screw. • Ask yourself: which type is often used where high maneuverability is needed, such as harbor tugs or certain ferries? • Consider which names in the choices refer to standard screw designs vs. a more complex disc-and-blade arrangement.

✅ Before You Answer

• Identify which option is known for exceptional maneuverability (thrust in almost any direction). • Eliminate the choices that are just variations of a conventional screw propeller on a shaft. • Match the description: flat disc flush with the hull + vertical rudder-like blades to the correct specialized propeller term.
