Hi,
I did get more information. The type of boat is a Pielego or pielago. It is a reduced version of the trabaccoli. From my research dimensions did not exceed 18 meters in lenght,5.5 meters in width and 2.4 meters in height with a capacity of 100 tons used for fishing and or loading of goods until early 20 century. The painting that I have is from a famous artist vincenzo luzzo.
