Your vessel's drafts are: FWD 22'-04", AFT 23'-06"; and the KG is 22.4 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the righting arm at 19° inclination if the center of gravity is 1.3 feet off center.

Question

Your vessel's drafts are: FWD 22'-04", AFT 23'-06"; and the KG is 22.4 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the righting arm at 19&deg; inclination if the center of gravity is 1.3 feet off center.

Accepted Answer

Option A: 0.2 foot. Determine the mean draft to select the stability curve. Find the GZ at 19 degrees for the 22.4-foot KG. Apply the correction: GZ_remaining = GZ_curve - (GG' * cos(19)). With a 1.3-foot transverse shift, the remaining righting arm is 0.2 feet.
