On a slightly different tack.... has anyone managed to cripple a target, i.e. damage its steering or propulsion and to actually see the results in game? I've repeatedly hit and nether regions of merchants with a deck gun just to see them maintain course almost regardless - unless my aiming is really bad (probably!

). I've seen targets change direction but I thought it was more to avoid my sub than results of damage.
Back on topic, I've just downloaded the critical hit mod in the d/l which supposed to change flooding values of tagets. No tried it yet tho.
