Is that true that American hydrophone was so much less capable than German's by only being capable to pick up ships at 10K yards? the four bearing method and 0° gyro attacks by hydrophone listening are possible for a very slow moving ship. Late in the war subs had radar, but before radar, how was that possible?

Observation. I do it in an S boat in SH4. A lot depends upon where you are versus where a target is when sighted, but it is possible to "get in position" in plenty of time, under the proper circumstances. You do miss more opportunities than you get though. My only issue is that an S boat has a ~slightly~ more difficult time getting away from a 1k yard or less shot though...
