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 ten days. You will consume 33 tons of fuel, water, and stores per day. The hydrometer reading at the loading pier is 1.021, and the average TPI is 51. What is the minimum freeboard required at the start of the voyage? Reference Table BL-0017 below.

Question

Accepted Answer

Option D: 72 inches. Compute minimum starting freeboard per Table BL-0017. Adjust for tropical-to-summer zone changes, dock water density at 1.021 with a TPI of 51, and 10 days of consumption at 33 tons per day, resulting in a minimum required departure freeboard of 72 inches.
