1. Get deep asap and rig for silent running, also set engine speed to less than 2 knots.

2. That is how it was in RL

3. For nagnetic settins you have to change the depth settings for the different draughts the ships have or you run the risk of the torpedo simply sliding down the underside of the keel.

4. There are so many to choose from so I'll pick one of my own....Q Ship mod.
