STABILITY CURVES
When a series of values for GZ (the ship’s righting
arm) at successive angles of heel are plotted on a graph,
the result is a STABILITY CURVE. The stability
curve, as shown in figure 12-24, is called the CURVE
OF STATIC STABILITY. The word static indicates
that it is not necessary for the ship to be in motion for
the curve to apply. If the ship is momentarily stopped at
any angle during its roll, the value of GZ given by the
curve will still apply.
