Your vessel's drafts are: FWD 19'-09", AFT 20'-09"; and the KG is 24.6 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the remaining righting arm at 15° inclination if the center of gravity is 0.5 foot off the centerline.

Question

Your vessel's drafts are: FWD 19'-09", AFT 20'-09"; and the KG is 24.6 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the remaining righting arm at 15&deg; inclination if the center of gravity is 0.5 foot off the centerline.

Accepted Answer

Option A: 0.0 feet. Determine the mean draft to select the correct stability curve. Find the GZ at 15 degrees for the 24.6-foot KG. Apply the correction GZ_remaining = GZ_curve - (GG' * cos(15)). With a 0.5-foot shift, the calculation results in 0.0 feet, indicating neutral stability.
