Using the Guidance Manual for Loading the 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 34 lbs.
AI Explanation
The correct answer is C) 1220 tons each.
The Guidance Manual for Loading the M.V. Grand Haven provides the necessary information to determine the required ballast in tank No. 3 (P & S) to maintain the specified drafts for a vessel loaded with grain at 34 lbs test weight. Based on the given drafts of 17'-00" forward and 22'-06" aft, the manual would indicate that 1220 tons of ballast is required in each port and starboard tank to achieve the desired trim.
The other options are incorrect because they do not match the ballast requirement specified in the guidance manual for the given vessel loading conditions.
