Help-Torp Depth/Sinking Escorts

On a more serious note...

Yes, the draft values used in RFB are not necessarily 100% accurate. They reflect the data available to the Allies in the form of the various ONI (Office of Naval Intelligence) manuals. In the case of that minesweeper, its reported draft was believed to be 6.1 feet.

Other things to note here:

Yes, that's as shallow as one can set the torpedoes. In reality, you wouldn't want them any more shallow than that, since they would broach the surface at any more shallow depth, in combination with rough seas.
Torpedo depth does not take into account whether the boat is submerged or on the surface. The TDC controls work the same in both conditions.
As I see you're playing in 1941, do note that all Mark 14 torpedoes will run between 10 and 11 feet deeper than the depth set by the TDC until about August 1942. Long story short, this was a result of incorrectly calibrated test instruments and failing to realize that a torpedo with a live warhead was heavier than when it was fitted with a practice warhead. As such, shallow-draft warships like these just aren't worth it for about the first 8 months of the war.
