In the scene in Taken where Brian Mills takes on the kidnappers on the boat, he appears to kill all the swarthy bad guys he encounters. This involves a lot of gun fire which would draw the attention of even the most incurious swarthy bad guy.
So who's driving the boat?
Presumably another swarthy bad guy, in which case wouldn't he grab his gun and join in the doomed attempt to thwart the unthwartable Brian? Or wouldn't Brian nip up to the cabin and pop a cap in his bottom to avoid any potential comeback? Who gets them back to dry land afterwards?
