How Do You Sink Ships In 1943 onwards...

Air craft a whole lot more.
Starting in 1943, when Adm King finally realized that the German subs meant business, air cover became the rule, with bases in Greenland, Iceland and finally, the Azores. In good weather, light escort carriers added further protection.
U-boats had nowhere to hide, and the war of the Atlantic was really over.
Almost all the U-boats after 1943 were sunk, and shipping loses for the Allies became minimal.
As for tactics after 1943, the best answer would be to transfer to the far East.

Why is transfering to the east the answer?
