    I heard the noise best when inside the boat.  I thought it was the teak
    walls expanding when our air conditioning had been running at first.  I
    would open the saloon door out to the aft deck and could not hear the
    sound, but later in the evening I stood upon the dock next to our
    vessel and could very clearly hear the sounds, almost as well as when I
    was inside the vessel.  I think therefore that the area under the docks
    was also being effected by the krill as well as the hull of the vessel.
      The sounds had more of a scraping component to them than what the gas
    bubbles of a school of herring would have (I think).
    
    The captain of our vessel said that he stayed one night at anchor at
    Dragon Point (Indian Harbor Beach, FL, ICW mile 914) a year or two ago
    when the noise was so loud that they could not sleep as a result.  The
    noise was so bad that he considered not staying at the same place
    again, but we needed to stay there again for this trip -- and of course
    there was no noise at all there this time. My observations were at the
    St. Augustine city marina.
