🔍 Key Concepts

• Meaning of Ro-Ro (Roll-on/Roll-off) vessels and how cargo is normally loaded/unloaded on them • Difference between cargo that must be lifted on with cranes vs cargo that can move on its own wheels or on wheeled platforms • Typical examples of cargo seen driving or being towed onto a Ro-Ro ferry or Ro-Ro cargo ship

💭 Think About

• Think about how cargo actually gets onto a Ro-Ro ship: does it need to be craned on, or does it roll on ramps? • For each option, ask: can this type of cargo be driven or towed on its own wheels onto the ship? • Consider whether Ro-Ro ships are limited to only one type of wheeled cargo, or if they can handle several related types.

✅ Before You Answer

• Be clear on the definition of Ro-Ro cargo (how it is handled, not what it looks like). • For each option, decide: does it involve rolling on wheels (self‑propelled or towed) via ramps? • Verify if any option is not normally associated with Ro-Ro operations because it needs lifting gear instead of ramps.
