I am close to an harbor and see a minesweeper,I wait for a 90 degrees shot and fired when the triangle went green(auto targeting).
Draft of the ship 2.9m,torpedodepth 2m...............torpedo too deep.

I set the torpedo depth to 1m.................too deep

What is wrong???
USS Narwhall (SS-167)
A sec.question:what do you do when you are on patrol with only sonar and no radar,do you dive every 4 houres to use the sonar,I read, to use the sonar,go to a few meters below periscope depth.
