Got it now, thanks!

For the first method, how do you usually proceed with acquiring a collision course? Do you go by first adjusting your boat's course port or starboard, until the bearing remains constant, then trim slightly as you proceed or is there a formula that can be used which assigns a probable bearing difference between the two ships' bow, for a given target speed?

What do you do if the bearing suddenly changes by 1-2 degrees after more than 15 minutes? For example, in situations in which you are intercepting a target by hydrophones over long range.
