I don't know if it's relevant, but in my fishing boat, if I pass astern of something like a ferry, then the depth sounder goes all screwy for a good distance behind the ferry, presumably due to aeration and/or turbulance. I would hazard a guess that this would persist for at least a good 60s after the ferry passes.
