It looks like a very early steam "lighter", forerunner to the puffers, and from which the "Puffer" gained it's name. The earliest of these steam lighters, without any form of superstructure over the boiler casing , and tiller steered, came about as early as 1856 and not until the 1890's were superstructures fitted.so this is a very early one indeed.
Also they were mostly converted steel dumb barges in the very early years and were not given names, just numbers.
you can actually see the tiller arm rising up from the rudder, on the photo.
This is probably a very old ship indeed. It is likely one of those constructed purely for working the Forth-Clyde Canal. This would explain its lack of bulwarks and apparent shallow draft. Before steamers, flat-bottomed horse-drawn scows were used on the canal.
