Care to actually explain your conclusion?

By the same token, if there was a ship far to the northwest going south - then it's the surfaced boat.
The submerged boat by sonar tracking over about 30-60 minutes track the sourse and speed of the boat, and then plot an intercept solution. Then surface and flank speed to this point, submerge and do the process again.
During this process batteries are charged, using less fuel compared to beating about the ocean.
The surfaced boat spotting the ship, visual or surface radar has to do the same thing.

Except radar also gives you accurate range, so your intercept solution is more or less automatic unless the target changes course.
