Question 2265 Deck Safety

The correct answer is D) 74 inches. The key factors here are the tropical load line mark at the port of loading and the summer load line mark at the destination port. Since the vessel will enter the summer zone after two days of steaming, the minimum freeboard required at the start of the voyage is determined by the summer load line mark, which is 74 inches according to Table BL-0021. The other answer choices are incorrect because they do not align with the summer load line mark requirement for the destination port. Choosing a freeboard lower than 74 inches would not meet the regulatory standards for the vessel's intended voyage.
