Question 677 Deck General

The correct answer is A) Lashings are always required. Under normal weather and sea conditions, lashings are required for securing a stack of containers with non-locking fittings, regardless of the height of the tier. This is a general safety requirement to prevent the containers from shifting or falling during transit. The height of the tier does not change the need for lashings, as the containers need to be properly secured at all times. The other options are incorrect because they suggest that lashings are only required after a certain height is reached, which is not the case. Lashings are necessary for all stacks of containers with non-locking fittings, regardless of the number of containers in the tier.
