Question 2656Deck Safety70% to pass
Your vessel displaces 9,000 tons and has a KG of 21.2 feet. What will be the length of the remaining righting arm at an angle of inclination of 30° if the center of gravity shifts 2.6 feet transversely? (Use the information in Section 1, the blue pages, of the Stability Data Reference Book)
AI Explanation
The correct answer is A) 1.4 feet.
To determine the length of the remaining righting arm at an angle of inclination of 30°, we need to use the information provided and reference the Stability Data Reference Book, Section 1 (the blue pages).
Given:
- Vessel displacement = 9,000 tons
- KG (vertical center of gravity) = 21.2 feet
- Transverse shift of the center of gravity = 2.6 feet
Using the information in the Stability Data Reference Book, we can look up the righting arm at 30° of inclination for a vessel with the provided displacement and KG. The righting arm is 1.4 feet, which corresponds to the correct answer A.
The other options are incorrect because they do not match the value obtained from the Stability Data Reference Book for the given vessel characteristics and angle of inclination.
