That's actually one piece of information that IS in the manual. It doesn't matter as much when shooting at merchants; I typically use half the draft there too unless I'm trying for a magnetic detonation, which needs to be a few feet beneath the keel. However, against warships, they have an armored belt to protect against explosions, including torpedoes, and the manual lists some rough guidelines on where to set them. They recommend 20 feet against battleships, I think 12 feet against cruisers, and I forget the rest. 20 feet+ has worked well on the 3 battleships I've sunk, though. 3 hits sunk a Fuso, 3 hits on another Fuso didn't sink it but did knock out one shaft and reduced its speed to 4 knots. The first one I encountered (an Ise) I hit with 6 torps and it just rolled right over.
