What procedure is commonly used to correct a large angle of list on a vessel?

The procedure to correct a large angle of list on a vessel involves shifting the center of gravity (CoG) toward the centerline. When a vessel lists, it indicates an imbalance where the CoG is offset from the vertical centerline of the hull. In order to regain stability and a more upright position, the CoG needs to be realigned with the centerline.

When the CoG is moved closer to the centerline, it creates a righting moment that helps to counteract the list. This is crucial for maintaining the equilibrium of the vessel and ensuring that it remains within safe operational limits. The process can involve reloading cargo or ballast, or other strategies designed to redistribute weight effectively.

The other options may not provide the most effective or safe method for correcting a significant list. For example, adding mass to the low side could exacerbate stability issues, while reducing weight from the middle of the ship might not address the primary issue of CoG displacement. Filling tanks to maximum capacity is also not a suitable corrective measure as it doesn't specifically address the alignment of weight and can lead to other stability concerns.
