A tanker loads at a terminal within the tropical zone. She will enter the summer zone five days after departing the loading port. She will burn off about 45 tons/day and daily water consumption is 8 tons. How many tons may she load over that allowed by her summer load line?

Correct Answer: Option D — 265

Calculate maximum allowable excess loading by accounting for total weight consumed during the voyage to the zone transition. Multiplying 5 days by the daily burn rate (45 tons fuel plus 8 tons water = 53 tons/day) gives 265 tons of consumed deadweight, allowing 265 extra tons at the tropical berth.
