How do Huck and Jim finally get away from the steamboat? CH 12-16

Having lost their raft, Huck and Jim search along the crashed ferryboat for the robbers' skiff. Just as they find it, the two robbers emerge and place the goods they have looted into the skiff. The robbers then remember that their partner still has his share of the money, so they return to steal it from him. Before they can return back to the boat, Huck and Jim jump into the skiff, cut the rope, and speed away downstream.
