Double Trip

The maneuver necessary when a towboat has more barges in tow than the power of the boat can handle in certain areas of swift current or conditions at the lock will permit. A tow will tie off below the swift water a portion of his tow, push the others above the questionable area, tie them off to the bank, and go back for the remainder of the tow. This is also a necessary maneuver in ice at times. (TNDOT1)
