      It was aft of the keel, on the canoe body underneath the cockpit. It wasn't
      installed until the last leg of the race from South America to the finish in
      Charleston, SC. There was precious little coverage at the time, but I
      distinctly remember reading about in on Compuserve Sailing forum so long

      | Don, I have not heard or don't remember any specific data on speed

      | John, I did not know about the keel thing on Thursday's Child and
      | would be skeptical that any naturally aspirated system could work on
      | a keel since it is so far below the water. Also, because of
      | increasing pressure, probably none of the air could get past the
      | highest openings in the keel if it did work at all.
