Yes, it is true sonic sounds could be picked up on the surface, but that only happened at very slow speeds. Now, given the way it's modeled now, do you want a surface sonar that's too good at picking up sounds (and thus pretty much rendering watch crews irrelevant) or one that's closer to reality? I'll take option B, thank you.

Cool link! Thanks!
