A cargo of 60 tons is to be loaded on deck 20 feet from the ship's centerline. The vessel's displacement including the 60 ton cargo will be 6,000 tons and the GM two feet. What would be the list of the vessel after loading this cargo?
• Effect of off-center weight on transverse center of gravity (TCG) • Relationship between shift in TCG, GM, and list angle • Using consistent units (tons, feet) and identifying total displacement vs. added weight
• Which formula connects the weight placed off-center, its distance from the centerline, the ships total displacement, and GM to give the tangent of the list angle? • How do you calculate the new transverse shift of the ships center of gravity caused only by the 60-ton deck cargo? • Once you have tan(θ), how do you convert that to degrees and compare it to the answer choices?
• Be sure you are using total displacement after loading (6,000 tons), not just the 60 tons, in the denominator of your formula. • Confirm that distance from centerline (20 ft) and GM (2 ft) are in the same unit system before calculating. • After finding tan(θ), use a calculator (or table) to get θ in degrees, then match it to the closest option.
