ok
seems to work
I don't use the lite harbour trafic and I let lose of the DBSM and now it works
had some serious fights with some DDs and took some damage... but more pescy are the flyboys...
seems to work
btw I am playing March 1943
I don't know if there is a big difference but I must admit that my old tactic playing cat and mouse with the DD is not working anymore... and I haven't seen a DD blow himself up with DCs
another thing I cannot comment so far is the speed the DCs need to get down... I have hunted in shallow waters so far... that is the reason for me getting bombed by flyboys

I just could not resist a convoy passing by
