Question 2325 Deck Safety

70% to pass

Your vessel's drafts are FWD 24'-09", AFT 27'-01". Use the information in Section 1, the blue pages, of the Stability Data Reference Book to determine the final drafts if 122 tons are discharged 76 feet aft of amidships, 128 tons are discharged 54 feet forward of amidships, and 68 tons of fuel is pumped 48 feet aft.

A FWD 24'-05", AFT 26'-02"
B FWD 24'-02", AFT 26'-11"
C FWD 24'-01", AFT 26'-08"
D FWD 24'-04", AFT 26'-08"
AI Explanation

The correct answer is D) FWD 24'-04", AFT 26'-08". To determine the final drafts, we need to calculate the change in trim and draft due to the given weight changes. Using the information provided in the Stability Data Reference Book, Section 1 (the blue pages), we can calculate the new drafts. Discharging 122 tons 76 feet aft of amidships causes the vessel to trim by the stern, increasing the aft draft and decreasing the forward draft. Discharging 128 tons 54 feet forward of amidships causes the vessel to trim by the bow, decreasing the aft draft and increasing the forward draft. Pumping 68 tons of fuel 48 feet aft causes the vessel to trim by the stern, increasing the aft draft and decreasing the forward draft. Considering all these weight changes, the final drafts are FWD 24'-04" and AFT 26'-08", as stated in option D. The other options are incorrect because they do not accurately reflect the changes in trim and draft based on the given weight changes.
