70% to pass

Using the information in Section 1, the blue pages, of the Stability Data Reference Book, determine the danger angle for permanent list if the KG is 22.4 feet and the drafts are: FWD 15'-03", AFT 15'-09".

A 25°
B 33°
C 48°
D 72°
AI Explanation

The correct answer is A) 25°. The Stability Data Reference Book provides tables and information to determine the danger angle for permanent list based on the vessel's KG (vertical center of gravity) and drafts. With a KG of 22.4 feet and drafts of 15'-03" forward and 15'-09" aft, the tables in Section 1 (the blue pages) indicate the danger angle for permanent list is 25°. The other answer choices are incorrect because they do not match the value provided in the reference material for the given vessel characteristics. The danger angle of 25° is the appropriate value based on the information provided.
