Go where the ships are....and use your hydrophone. Or wait until you get a radio contact report....and intercept.

One you have a sound contact I personally surface and go straight at the sound contact at full or flank for 15 minutes and dive again for another sound reading. I try and figure out how much (how many degrees) the target has moved.... then double the intercept angle. IE: if the contact drifted 10 degrees right of my current course.....I would turn right 20 degrees when I surface again to create a crude intercept angle. I would then full or flank for 30 minutes and do another sound check to see if there is any drift...then I would correct again. What you are looking for is CBDR or Constant Bearing Decreasing Range...which means you are on the proper intercept course. IE: if the sound contact (from above) drifted 10 degrees right after your second reading ...then you correct 20 degrees right (putting the sound contact 10 degrees to the left of the bow), then after 30 mins you do another sound check.... if the sound contact is still at 10 degrees left ..you have CBDR. Anyway I think the game only renders sounds inside of 30 KM (which is BS) (can someone confirm this please) so chances are you'll see them before you have to make too many dives for updates.

You're only source of info for ships is your own sound/visual pickups and contact reports (Red boxes on your map). You can use your stock shipping traffic map to help..... but it's still hard to find them.
