Using TMaru or RFB I've hit merchants a lil forward of the pilot house and MOT with more than 1 torp and they burn forever and their bows sink below the gunnel with green water up to the portholes on the wheelhouse, but they butts stay afloat and rejoin the convoy; however, I've accidentally hit merchants abaft the wheel house with one torp and they DO become dead in the water and slowly sink. The large tankers seem to slip under with one torp when hit in the abaft superstructure at the stack.
