Re "The Veneti ships bear a striking resemblance to the Viking trading vessels known as knarr which researchers persist in calling 'Gallo-Roman' ships notwithstanding. "
As with many things, some "researchers" get it back to front (or seriously sideways). The Roman invaders captured over 200 Veneti ships in the in 56 BCE, between the Romans led by Decimus Junius Brutus Albinus. This naval battle was later immortalised in Julius Caesar's Gallic Wars (Volume Three)
'The Gauls' [Veneti] ships were made with much flatter bottoms [than Roman ships] to help them ride shallow water caused by shoals or ebb tides. Exceptionally high bows and sterns fitted them for use in heavy seas and violent gales, and the hulls were made entirely of oak, to enable them to stand any amount of shock and rough usage. The cross-timbers, which consisted of beams a foot wide, were fastened with iron bolts as thick as a man's thumb. The anchors were secured with chains instead of ropes. They used sails of raw hides or thin leather, either because they had no flax and were ignorant of its use, or more probably because they thought that ordinary sails would not stand the violent storms and squalls of the Atlantic and were not suitable for such heavy vessels … adapted for sailing such treacherous and stormy waters. We could not injure them by ramming because they were so solidly built, and their height made it difficult to reach them with missiles or board them with grappling irons. Moreover, when it began to blow hard and they were running before the wind, they weathered the storm more easily; they could bring in to shallow water with greater safety, and when left aground by the tide had nothing to fear from reefs or pointed rocks.'
The Romans recognised superior Celtic technology when they found it, and would have put some or many of the captured Veneti trading ships into use as part of their fleet. These were big craft with covered decks, with a capacity of c.200 cubic metres.
The Viking Knarr vessels were much smaller, open desk, clinker built and often propelled by oars as well as sail, to suit their role as river or coastal boats.
