Question 901 Deck General

The correct answer is D) The size, weight, and center of gravity of vehicle/cargo unit. When loading and securing vehicles aboard a Ro-Ro vessel, the key concern is ensuring the stability and safety of the vessel. The size, weight, and center of gravity of each vehicle or cargo unit are critical factors in determining the proper stowage and securing methods. This information allows the crew to distribute the load evenly and secure the vehicles in a way that prevents shifting during the voyage. The other options are incorrect because: A) Draining fuel is not necessarily required, as long as the vehicles are properly secured. B) Leaving the brakes off can make it harder to adjust the lashings. C) Athwartships stowage is preferred, but not always possible depending on the cargo configuration.
