Question 450 Deck General

The correct answer is D) With tiered containers, a 40-foot container may be stowed on top of two 20-foot containers. This is correct because the stacking of containers is governed by stability and load-bearing considerations. It is common practice to stack a 40-foot container on top of two 20-foot containers, as the weight distribution and support requirements can be properly accounted for. The other answer choices are incorrect: A) Deck load calculations must take into account the entire container bottom area, not just the square footage. B) The bottom of the container does not need to be evenly supported throughout when stowed on deck, as long as the overall stability and load-bearing requirements are met. C) The stowage plan should be prepared in advance, but it is not specifically the responsibility of the Chief Mate and Master to have it ready for the stevedore upon arrival.
