Your Ro Ro vessel has just completed discharging the lower decks and is commencing discharging the upper levels. What would it indicate if the vessel were to suddenly develop a list?

Correct Answer: Option D — if the cargo has been discharged symmetrically it is an indication of negative GM

A sudden list during symmetrical cargo discharge on a Ro-Ro vessel is a classic indicator of negative GM. When the center of gravity rises above the metacenter, the vessel loses its ability to remain upright, resulting in an angle of loll where the ship becomes unstable and shifts to one side.
