Question 2195 Deck Safety

The correct answer is D) hydrostatic curves. Transverse stability calculations require the use of hydrostatic curves, which provide information about the vessel's stability characteristics. Hydrostatic curves plot the vessel's properties, such as displacement, draft, and righting arm, against changes in the vessel's trim and heel. These curves are essential for determining the vessel's transverse stability, as they allow for the calculation of important stability parameters like the metacentric height (GM). The other options are not directly used in transverse stability calculations. General arrangement plans and cross-sectional views provide information about the vessel's geometry, but do not contain the necessary data for calculating transverse stability. Hog or sag calculations are related to longitudinal strength, which is a different aspect of vessel stability.
