Using the Guidance Manual for Loading M.V. Grand Haven, determine the amount of ballast required in tank No. 3 (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 37.6 lbs.

Correct Answer: Option C — 975 tons each

Cargo capacity and hydrostatic tables in the M.V. Grand Haven Guidance Manual dictate that exactly 975 tons of ballast must be loaded into both port and starboard tank No. 3 to achieve the required 17'-00" forward and 22'-06" aft drafts.
