[Paul Riley]

I sometimes use salvos,either against a vessel of say 10.000 tonnes and above,or against the flank of a convoy.
If I opt for a salvo shot (for whatever reason I feel it neccessary) it will only ever be done at short ranges anyway,I very rarely if EVER attack at long distance.

NOTE - Salvos can be very effective at close ranges,and if you get the spread angle just right you can 'kill' a ship quickly and efficiently by striking vulnerable points practically instantaneously.
