A vessel displaces 12,000 tons and has a KG of 22.8 feet. What will be the length of the remaining righting arm at an angle of inclination of 60° 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)

Question

Accepted Answer

Option D: 1.9 feet. Retrieve the 60° righting arm from Section 1 stability curves for a 12,000-ton vessel with a 22.8-foot KG. Subtract the transverse displacement correction ($1.8 	imes \sin 60°$) to calculate the accurate remaining righting arm of 1.9 feet.
