Which of the following propulsor types does not require the use of a separate rudder for steerage?

Question 1 of 27070

Which of the following propulsor types does not require the use of a separate rudder for steerage?

🔍 Key Concepts

• How steering is produced on different propulsor types (by a rudder vs by redirecting thrust at the propeller itself) • What a separate rudder is and when it is normally needed • Specialized propulsors that can generate thrust in any horizontal direction without turning the ship

💭 Think About

• For each option, ask: Does this arrangement still rely on water flowing past a rudder blade, or can it change thrust direction on its own? • Think about which propulsor type is often used on tugboats and ferries for very precise maneuvering without a large rudder. • Which of these is a "conventional" layout with the propeller fixed on a shaft and a rudder behind it, and which one is fundamentally different in how it steers?

✅ Before You Answer

• Be clear on the definition of a separate rudder (a distinct steering surface behind the propeller). • Identify which propulsor type can vector thrust 360° (in any direction) without needing a rudder to turn the flow. • Confirm that tandem and contra-rotating describe how multiple propellers are arranged on a shaft, not a built‑in steering system.
