Using the Guidance Manual for Loading M.V. Grand Haven, determine the amount of ballast required in tank No. 5 (P & S) to maintain drafts of 17'-00" forward and 22'-06" aft for a vessel loaded with grain which has a test weight of 35 lbs.

Correct Answer: Option C — 880 tons each

Hydrostatic calculations and loading tables for the M.V. Grand Haven specify that maintaining target drafts of 17'-00" forward and 22'-06" aft with a 35 lb grain test weight requires precisely 880 tons of ballast in each of No. 5 port and starboard tanks.
