the only thing i wonder is, how come when he used the arm to raise himself onto the barge (therefore pushing away from land) the boat didnt move, yet when he used the arm again once onboard to push away from the dirt the barge moved immediately? im not saying at all this is fake, more a point on just how good this guys technique is
The barge bow didn't move because it was 'beached' on the sand ... it took the boom of the excavator to push the barge off the sand, to allow water beneath the bow, so the barge could again move ...
