The idea of the "spread" or "fan" shot is not to hit multiple parts of the ship (even though that is very likely to happen) but rather to fire several torps at once at slightly different directions in the hope that at least one of them hits. Tactical situations where this could come in handy are when you're firing solution data isn't trust worthy (like when you don't know the enemy's exact speed, for example).
If your intent is to target several "key" parts of the target at once, I suggest you go with the "firing one by one in rapid succesion" method, taking care to point each torp into the desired compartment (always remembering to open the tube doors).
