Study Notes

IMO Grain Rules

Initial metacentric height is calculated after correcting for the free surface effects of liquid in tanks.

Ship Design and Safety Features

Freeboard is the distance between the main deck and the waterline, a critical factor in determining a ship's stability and safety.
Bilge keels are longitudinal structures running along the bottom of a ship's hull, serving to reduce the rolling motion and improve stability.
