Question 2301 Deck Safety

70% to pass

Your vessel is limited to a maximum draft of 26'-03". The present drafts are: FWD 22'-10", AFT 23'-08". How much more cargo can be loaded and where should it be located if a drag of 18 inches is desired? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book)

A 875 tons 6 feet aft of amidships
B 950 tons 8 feet forward of the tipping center
C 1323 tons 7 feet aft of the tipping center
D 1452 tons 7 feet aft of the tipping center
AI Explanation

The correct answer is C) 1323 tons 7 feet aft of the tipping center. To arrive at this answer, we need to use the information provided in the Stability Data Reference Book, Section 1 (the blue pages). Given that the vessel has a maximum draft of 26'-3" and the current drafts are 22'-10" forward and 23'-8" aft, we can calculate the available freeboard and the additional cargo that can be loaded to achieve the desired 18-inch draft. Using the stability data, we can determine that an additional 1323 tons of cargo loaded 7 feet aft of the tipping center will result in the desired 18-inch draft, which is the correct answer. The other options are incorrect because they either do not match the desired draft or the cargo location is not optimal for the vessel's stability.
