Usually we tend to go for the straight torpedo run attacks as if the torpedo was a bullet or an arrow. The torpedo can however change its course after the initial launch, a bit like a tennis ball or a soccer ball can be hit with a curve. One can for example run alongside a ship and shoot the torpedo towards a ship that you see exactly to your right or left while moving to the same direction it is travelling. The reason we don't often do that is the need for accurate estimations and the fact that the eels fail us with the depth keeping and pistol already. The turning of the torpedo is yet another aspect that might fail. But if a launch like that succeeds the torpedo will hit the ship's hull at a 90 degree angle, even if the u-boat is not at a 90 degree angle.
