Question 2557 Deck Safety

The correct answer is B) Available GM 3.9 ft. To determine the available GM (Metacentric Height), you need to use the stability data provided in the table ST-0059 and reference the white pages of The Stability Data Reference Book. Based on the information given in the table, the available GM is 3.9 ft, which corresponds to answer choice B. The other answer choices are incorrect because they do not match the GM value obtained from the reference book. Answer A (3.2 ft) and C (4.8 ft) are too low or high, respectively, while answer D (5.3 ft) is also incorrect.
