I have read all the arguments online: Hydrophone on chin allowed submarines to hear enemy ships while surfaced, crews trained in listening while on surface, chin hydrophones could only hear high frequency sounds such as pinging and so forth.

I have also read several submarine ships logs, where no record of locating enemy ships using the hydrophone while surfaced was recorded.

If discussion of this issue is an option, I would like to hear what others think. If powers that be have decided this issue is closed for FOTRS, please let me know.

Thanks.
