Your vessel's drafts are: FWD 27'-06", AFT 28'-02"; and the KG is 23.1 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the righting arm at 37° inclination if the center of gravity is 1.8 feet off center.

Question

Your vessel's drafts are: FWD 27'-06", AFT 28'-02"; and the KG is 23.1 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the righting arm at 37&deg; inclination if the center of gravity is 1.8 feet off center.

Accepted Answer

Option A: 0.4 foot. Calculate the mean draft to identify the correct stability curve. Extract the GZ value at 37 degrees for the specified KG. Apply the transverse shift correction: GZ_remaining = GZ_curve - (GG' * cos(theta)). Using 1.8 feet for GG', the resulting righting arm is 0.4 feet.
