Safety & Environmental Protection (Deck) USCG Question #2189 (Set 67)

You are loading in a port subject to the tropical load line mark and bound for a port subject to the winter load line mark. You will enter the summer zone after steaming six days. You will enter the winter zone after an additional three 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 46. What is the minimum freeboard required at the start of the voyage? Reference Table BL-0012 below.

Official USCG Answer & Rule Citation

Correct Answer: Option B — 64.5 inches

Calculate minimum departure freeboard using Table BL-0012 for a tropical-to-winter transit. Account for seasonal zone allowances, dock water density (1.020), TPI (46), and total consumables burned over the 9-day voyage (28 tons/day), resulting in a required freeboard of 64.5 inches.
