Question 2067 Deck Safety

The correct answer is A) the vertical distance from the main deck plus the vertical distance to the head of the boom. When calculating the center of gravity as containers are discharged from the main deck, the key factor to consider is the location of the load relative to the ship's structure. The center of gravity will shift as the load (the containers) is moved vertically from the main deck to the boom tip. Therefore, the correct answer is the sum of the vertical distance from the main deck to the boom head, as this represents the full vertical displacement of the load. The other options are incorrect because they do not fully account for the vertical movement of the load from the main deck to the boom tip. The height of the container alone is not sufficient, as the boom position also affects the center of gravity.
