Pontoon ferries carry vehicles across rivers and lakes and are widely used in less-developed countries with large rivers where the cost of bridge construction is prohibitive. One or more vehicles are carried on a pontoon with ramps at either end for vehicles to drive on and off., The pontoon ferry on the stamp is motorised and able to be steered independently like a boat.
I have not any info or details on the pontoon ferry depict on the stamp.
