70% to pass

You are loading in a port subject to the tropical load line mark and bound for a port subject to the summer load line mark. You will enter the summer zone after steaming two days. You will consume 28 tons of fuel, water, and stores per day. The hydrometer reading at the loading pier is 1.020, and the average TPI is 55. What is the minimum freeboard required at the start of the voyage? Reference Table BL-0021 below.

A 62 inches
B 66 inches
C 70 inches
D 74 inches
AI Explanation

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.
