Your vessel's drafts are: FWD 21'-04", AFT 21'-08"; and the KG is 20.6 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the remaining righting arm at 45° inclination if the center of gravity is 1.2 feet off the centerline.

Question

Your vessel's drafts are: FWD 21'-04", AFT 21'-08"; and the KG is 20.6 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the remaining righting arm at 45&deg; inclination if the center of gravity is 1.2 feet off the centerline.

Accepted Answer

Option B: 4.4 feet. Find the mean draft and use the stability curves to determine the GZ at 45 degrees for a 20.6-foot KG. Apply the transverse shift correction: GZ_remaining = GZ_curve - (GG' * cos(45)). With a 1.2-foot shift, the resulting righting arm is 4.4 feet.
