I just did a little research & found that some, if not all, British trawlers were in fact fitted with ASDIC (sonar).
My confusion arose by noticing that the depiction of trawlers on the navigation map does not include the dotted half circle directly in front of them that destroyers have, which, I assumed, showed the detection range of their sonar.
Still not sure whether active sonar on trawlers is implemented in the game, but I suppose I can find out by saving first & then making a lot of noise while submerged & near one of them..
