Thanks a lot RoaldLarson,

Quite helpful,the 20km dash you described,its akin to what I was doing previous,I draw a 20km circle either side of the expected route,and move to the centre of the 1st,dive,listen,surface,move to the edge,repeat,then move onto the 2nd circle and repeat all the previous,however I only do it at the convoy's expected speed,say no more than 8kts.This is not practical at all the more I think of it,because while I am patrolling the 1st cirlce at 8kts,a target could move through the 2nd circle and be gone by the time I reach that area.Your high speed patrolling sounds more effective,but wouldnt this sap fuel much quicker?,which could be better saved for extended patrols that could go into weeks?.
I am confident I may be on the AK48 route,according to the game map that is,but we shall see.
I just wish there was some info on the web,i'd like to know more about patrol tactics.

Well,thanks again for the reply.
