- To calculate ship stability, you need to:
- Calculate metacentric height (GM).
- Calculate and plot righting arm curves (GZ).
- Calculate changes in drafts and trim for weight additions, removals, or shifts.Remember that GM > 0 indicates stability, GM = 0 is neutral stability, and GM < 0 means instability12.

Specifically, calculate metacentric height (GM), calculate and plot righting arm curves (GZ), and calculate changes in drafts and trim for weight additions, removals, or shifts.www.usna.edu/NAOE/academics/en342.php- GM > 0 means the ship is stable.
- GM = 0 means the ship is neutrally stable.
- GM < 0 means the ship is unstable.

Ship stability - Wikipedia
In order to be acceptable to classification societies such as the Bureau Veritas, American Bureau of Shipping, Lloyd's Register of Ships, Korean Register of Shipping and Det Norske Veritas, the blueprints of the ship must be provided for independent review by the classification society. Calculations must also be provided which follow a structure outlined in the regulations for the country in which the ship intends to be flagged.
