Question 4671 Deck General

The correct answer is A) 1S. The reasoning is that in a situation where the vessel is listing to port and trimming down by the stern due to flooding in the port aft column, counterflooding tank 1S (the starboard forward tank) would help to counteract the port list and stern down trim. By flooding tank 1S, the vessel's stability and trim would be restored, preventing further loss of control. The other options are incorrect because: B) C2BS is not a tank on the vessel, C) 1P is the port forward tank which would exacerbate the port list, and D) 10S is the starboard aft tank which would not effectively counteract the stern down trim.
