Transverse stability calculations require...

🔍 Key Concepts

• Transverse stability deals with how the ship resists rolling from side to side • Which vessel data gives you displacement, KM, KB, and righting arms (GZ) at different drafts and heel angles • Difference between plan drawings (how the ship is laid out) and stability data (how the ship floats and returns upright)

💭 Think About

• Ask yourself: When you do a GM or GZ calculation, what specific numerical data or curves do you normally look up in the stability booklet? • Which choice actually provides you with values that change with draft and water density, rather than just showing the vessel’s layout or shape? • Think about what information you need from tables or graphs to plot a righting arm curve or evaluate initial stability.

✅ Before You Answer

• Identify which option contains tabulated/graphical hydrostatic properties (like displacement, KM, KB, drafts) versus simple drawings • Confirm which source you would use directly in a GM (metacentric height) or GZ (righting arm) calculation • Eliminate any choices that only show layout or structure but do not provide numerical stability data across drafts

Transverse stability calculations require the use of which information?

Hydrostatic curves

General arrangement plans

Cross-sectional views of the vessel

Hog or sag calculations or tables
