Das Boot surface attack at flank speed - how?

I tryied once in sh3, a convoy not reported, a manage to get parallel to them (1940 of course), at medium speed and lock on one of the outside targets to measure cousre and speed and plot it on the fly on the nav map. Use the compass for range, protactor for angle. I managed to get the speed and course right and at about at 3 or 4 filometres i turnded to about 20º off their perpendicular, once i had plotted the solution on the map and introduce it to the TDC. I launched a salvo and turned outside their path at my fastest speed. I was ready to be persuited for a while and then crash dive, but nobady seemed to care about me. I hit 2 targets, lucky shot. There was a gap in the escorts, not enough, you have to find the gaps and have luck.

Also, i was thinking as i am no expert, that tey did his is the one thing that breaks sh3, there is no wolfpack. I suppose that what they did was tryied this with 2 or 3 u boats in a night, and as most failed and were force to evade they dislocated the guard, and then it came the lucky one that got the convoy all mest up and with no escorts. I he was the one that sunk at pleasure, so maybe those heroes that got those big tonnages were just the ones that were at the right place at the right moment. And that just worked for a while, cause no yanki aint stupid...i suppossed. Also the u boats are the nown ones, but after learning about us sillent service, i think in overall they were far superior.

Section VII :

(b) When attacked at Night. Night attacks on U-boats are in the nature of things generally made in the vicinity of convoys. Whether the U-boat is attempting to attack on the surface or has been detected submerged the tactics may well be to surface as soon as possible and escape at high speed.

(c) Asdics. Some of the limitations of the asdic are known to the enemy. It is realised that contact must necessarily be lost when running in to attack and sometimes as soon as the attacking vessel is committed U-boats increase to full speed and work their pumps if required. Many commanding officers endeavour to keep their boat bow or stern on to the attacking vessel in order to give the narrowest extent of target. The ping of transmission can be heard by hydrophones in a U-boat at greater range than that at which it is first possible to get an echo. When the A/S vessel is at close range the transmission can sometimes be heard aurally.

(d) U-boats sometimes deliberately allow themselves to be sighted while other boats in the vicinity get away or attack without interference.
