Some questions regarding real navigation

[Compans57]

I've reached the point whereby I'd like to implement this into the game. The whole idea of working 'blind' seems like it'd add a rawness and realism to the whole thing. I have a few reservations though. I'm wondering if anyone could give me their opinion:

- The 4 bearing method seems very involved and quite complicated. Is it necessary to go through the whole sequence for every contact? I'm thinking that much of the time the contact is a warship or warship group that you're trying to leave at a distance. Is there a simplified method to determine where they are that doesn't involve so many marks and compasses etc?

- I have the annoying bug a lot, whereby a warship or several will attach itself to my sub at a distance and follow, in a circle pattern also at a distance. The only way to stop this is to save and reload the game. As it's obvious when this happens with symbols on, I would imagine it's far less so with real navigation. How do players deal with this?

Thanks.
