Depends. I could really use help here in determining how efficient the keel-mounted sonar was at detecting plain-old ship noises while on the surface, i.e., up to what general speed.
Whatever ahead slow would equate to in kts. This as per the USS Batfish and tactic used so the sonar could be used while surfaced. I guess somewhere between 3-5 kts. After that the sonar should have muddled sounds and water sounds going around the hull.
