The crafts and traditions of the old canal community developed from the distinctive lifestyle of the boatmen and women who lived out their lives in the confines of the canal system of the 19th Centuary.
It was short lived as we think of time today, lasting only about 200 years.
The boats origanally were crewed on a daily basis, it was the coming of the railways which promoted the living boats that we think of when we refer to the traditional narrow boats.
Roses and castles spring to mind when we think of boat decoration.
No one is sure where this originated from, the narrow boats came before the gypsy vardohos, so this could not have been the origin.
From personal observation they do seem to resembol the paintings on the bows of Spanish fishing boats, and Arab dhows have traditional signs to give them good luck, so maybe the just evolved from many traditions.
what does it matter, they are attractive in their own right so let us just enjoy the crafts of the waterways and be thankful that they are still with us today.
