which is the easiest way to sinking ships in GWX3?

For that particular vessel that method will yield only wasted eels. The listed draft of the Aquitania in SH3 is wrong. Her draft was actually 36 feet/11meters and is modeled as that in game. There was a thread about this only the other week actually.
As for other ships I usually set the torp to magnetic fuse about half a meter below the vessel's indicated keel, that way if she's sitting higher due to waves she's not outside the fuse's range and if she's lower I get an impact detonation. While the latter doesn't cause as much damage it's still a wholly below waterline hit and is better than a wasted eel.
