Advanced hydrophone lessons - calculating speed?

Paul Riley · 03-11-10, 09:17 AM

I would like to begin a thread on advanced Hydrophone lessons ( not sure if they have been done before ) as I want to start getting used to gathering ship data without ever having to raise the scopes,ideally for late war scenarios or against warships.Initially I am wondering how to get quite reliable results on speed.I understand the theory in counting revolutions to get speed but don't know how to do it correctly,or even how to translate this data into speed results.
If there is a link to this info you could direct me to that,or just teach me from scratch,your choice

I can say once I am close to mastering advanced hydrophone use to gather data I can start to enjoy the finer points of commanding a UBoat.
Maybe the next lesson could be 'determining ship course when submerged' ?
