Question 160 Deck General

The correct answer is A) 23 tons each. To determine the amount of ballast required in tank No. 1 (P&S), we need to consult the Guidance Manual for Loading the M.V. Grand Haven, which provides the necessary information to maintain the desired drafts of 17'-00" forward and 22'-06" aft for a vessel loaded with grain with a test weight of 43 lbs. According to the manual, for a vessel with these specifications, the required amount of ballast in each tank No. 1 (P&S) is 23 tons. The other answer choices are incorrect as they do not align with the guidance provided in the manual for this specific vessel and loading condition.
