Question 866 Deck General

The correct answer is D) rapid loading and discharge. Cargo securing for Ro-Ro (roll-on/roll-off) vessels is based on the concept of rapid loading and discharge. Ro-Ro vessels are designed to efficiently load and unload cargo, often vehicles, through ramps. This requires the cargo to be secured in a way that facilitates quick and easy loading and unloading, rather than other cargo handling methods like palletized cargo or solid packing. The other options are incorrect because they do not align with the specific requirements and operations of Ro-Ro vessels. Ro-Ro cargo is not loaded to the vessel's marks, nor is it typically palletized or solid-packed, as these methods would not support the rapid turnaround times required for this type of vessel.
