Although never again reaching the heights of the late 1920s, Thames continued to be successful through the thirties and then, after the Second World War, into the forties and fifties. However, in the early sixties the club began to experience a marked decline in membership and standards. By the early seventies Thames had very few active members and came close to bankruptcy. The club went for 47 years from 1956 without a win by a men's crew at Henley Royal Regatta.
