Your vessel's drafts are: FWD 23'-01", AFT 24'-05"; and the KG is 22.8 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 1.9 feet off the centerline.

Question

Your vessel's drafts are: FWD 23'-01", AFT 24'-05"; and the KG is 22.8 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 1.9 feet off the centerline.

Accepted Answer

Option A: 0.7 foot. Calculate the mean draft to select the correct stability curve. Find the GZ at 30 degrees for the 22.8-foot KG. Apply the correction formula: GZ_remaining = GZ_curve - (GG' * cos(30)). With a 1.9-foot transverse shift, the remaining righting arm is 0.7 feet.
