Was asking myself the same while reading.
First of all, thanks for your work and for sharing
Some Questions I have:
How do you find out the RPM and speed from the tanker?
Can you be sure that the target is at 34km? Doesnt it depend on seastate and depth how far a noise can be heard via sonar? How do you know that the target is not around for some time already. are you manning the sonar manually _all the time_ to spot it as soon as it shows up?
What is the north-south line, centered on "Mark 1" good for?
