Question 2560 Deck Safety

The correct answer is C) Available GM 3.5 ft. To determine the available GM (Metacentric Height), you need to use the white pages of The Stability Data Reference Book and the load information provided in table ST-0184. By looking up the relevant data in the reference book, you can find the GM value that corresponds to the given load condition, which is 3.5 ft. The other options are incorrect because they do not match the GM value obtained from the stability data reference. Option A (2.8 ft) and Option B (3.2 ft) are too low, while Option D (3.8 ft) is too high compared to the correct value of 3.5 ft.
