The tutorial I've recommended to you is useful for plotting an intercept course knowing the course and speed of your target. The method is still valid for hydrophone contacts, except for the fact that you have to find by yourself its speed/course. You can do it by using the
four bearings method 
@ flostt
the thread suggested by you seems interesting, but the download doesn't work, at least for me
