Your vessel's drafts are: FWD 17'-07", AFT 16'-09"; and the KG is 21.5 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the remaining righting arm at 30° inclination if the center of gravity is 0.9 foot off the centerline.

Question

Your vessel's drafts are: FWD 17'-07", AFT 16'-09"; and the KG is 21.5 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the remaining righting arm at 30&deg; inclination if the center of gravity is 0.9 foot off the centerline.

Accepted Answer

Option B: 2.8 feet. Determine the mean draft to identify the correct stability curve. Extract the GZ at 30 degrees for the 21.5-foot KG. Apply the correction: GZ_remaining = GZ_curve - (GG' * cos(30)). With a 0.9-foot transverse shift, the final remaining righting arm is 2.8 feet.
