Hi mate.

1. Even on busy routes at any time of war you could pass 24 hours without seeing a ship. Not unusual at all early on, especially if you get 'quiet' grid.

2. You don't return to port after 24 hours. Most people go where they like after the patrol period or you could add realism by patrolling it longer or assigning yourself another grid. Most people return to port only once the torpedos are finished.

3. Pretty much as above.

4. No experience of manual targeting, sorry.

5. Is it maybe once you've re-surfaced he's not there? You need to re-assign the watch crew to the con once you've surfaced. Then his icon will appear again.
