Reference Answer
(a) Permissible Length
Permissible length refers to the maximum length of a ship's compartment that can be flooded while ensuring that the sinkage, heel, or trim remains within acceptable limits without exceeding the floodable length. It ensures the ship remains afloat and stable after flooding.
Permissible Length Formula:
$$Permissible\:lenght\:=\:Floodable\:length\:\times Factor\:of\:subdivision$$
