Using the Guidance Manual for Loading the 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 33 lbs.

Correct Answer: Option D — 1070 tons each

Consulting the M.V. Grand Haven Guidance Manual, the hydrostatic tables and loading curves for the specified grain test weight of 33 lbs require 1070 tons of ballast in tank No. 5 (P & S) to achieve the target draft of 17'-00" forward and 22'-06" aft.
