In this tutorial we will set weights and tanks for our series 60 ship, in a simulated situation. Area involved by GZ curve from 30 to 40 degrees of roll angle must be at least 0.030 m.Area involved by GZ curve up to 30 degrees of roll angle must be at least 0.055 m.Area involved by GZ curve up to 40 degrees of roll angle must be at least 0.090 m.With 30 degrees roll angle, GZ value must be 0.2 m at least.Maximum GZ value must be placed over 30 degrees of roll angle.GM (metacentric height) is the initial tangent of the GZ curve. IMO (International Maritime Organization) set following criteria: GZ is the static moment generated when the ship takes roll angle, of course, since the GZ arm is positive, the ship has a positive moment, and will try to recover upright position, but when GZ turns on negative numbers ship has not anymore stability, reaching a critical situation. In this tutorial we will work with weights and tanks in order to compute GZ curve, the most important hydrostatic stability parameter.
