70% to passYour vessel displaces 12,000 tons and has a KG of 22.6 feet. What will be the length of the remaining righting arm at an angle of inclination of 30° if the center of gravity shifts 1.8 feet transversely? (Use the information in Section 1, the blue pages, of the Stability Data Reference Book)
A
0.8 foot
B
1.2 feet
C
1.8 feet
D
2.3 feet
AI Explanation
The correct answer is A) 0.8 foot. The length of the remaining righting arm at an angle of inclination of 30° can be calculated using the formula provided in Section 1 of the Stability Data Reference Book. With a vessel displacement of 12,000 tons and a KG of 22.6 feet, along with a transverse shift of the center of gravity by 1.8 feet, the resulting righting arm length at 30° is 0.8 foot. The other answer choices are incorrect because they do not accurately reflect the calculation based on the given information and the formula provided in the reference material.
