It is the moment just before the vessel takes blocks overall.

It can be calculated by following formula: |
Pmax = MCTC X t / l
MCTC = Moment to change trim by 1 cm.
t = Trim in cm.
l = Distance of CF from AP.
|
|
It is called critical instant because maximum loss of GM occurs at this instant. |
|
|
If GM becomes negative, the ship may capsize or slip from block. |
