Which of the following statements is TRUE...

🔍 Key Concepts

• Ro-Ro (Roll-on/Roll-off) vehicle securing practices and why vehicles can shift at sea even with brakes set • Effect of lash angle on holding power and risk of sliding versus tipping • Difference between securing for road transport vs. sea transport (combined motions, accelerations, and directions of forces)

💭 Think About

• Think about what happens to vehicles on a car deck in heavy rolling and pitching: would brakes alone prevent all movement? • How does the angle of the lashing affect its ability to resist movement in different directions (fore‑and‑aft, athwartships, and vertically)? • Which statement aligns with the idea that sea motions are more severe and multi‑directional than road motions, and lashings must account for that?

✅ Before You Answer

• Check which options clearly contradict basic safety practice you know from real-world Ro-Ro operations (for example, are cars ever sailed without lashings in bad weather?). • Verify which option correctly describes a generally recommended lash angle limit relative to the deck (too flat vs. too steep). • Confirm which answer, if applied in practice, would most reduce the risk of vehicles shifting during heavy weather, based on both direction of stowage and securing.

Which of the following statements is TRUE regarding lashing requirements to secure vehicles aboard Ro-Ro vessels?

It is NOT imperative that the securing of cargo on flats and trailers and in containers be adequate for BOTH road and sea motions.

For effective securing vehicles should be stowed athwartships whenever possible.

It is not necessary to lash automobiles since setting the brakes is sufficient to keep them from moving.

The generally recommended lash angle should not be greater than 45 degrees relative to the deck in any direction.
