Hi!
The sonar blind spot is (in real life) not a constant, but dependent on the type of sonar and the depth of the U-boat. Early war sonars had a relatively shallow angle (say, 10-15 degrees wide just below the surface); this rewarded deep-diving submarines, since the range at which the surface ship lost contact increased as the submarine went deeper. Basic geometry gives a reasonably good first approximation of the size of the blind spot at different depths.
Later sonars had narrower beams but could look down at about a 70 degree angle, as well as looking to the side, resulting in a much smaller "blind spot" and giving a fairly accurate reading of the U-boat's depth.
In addition, destroyers developed a tactic where one ship would stand off and use its sonar to track the submarine while radioing directions to the close-in "blind" ships moving in for the kill.
It's not clear how well (if at all) SH3 models this kind of behavior or allows it to be modeled.
