Mike – yes, I’d be happy that those were reasonably representative of what I have read was possible. I might dispute a few details but mostly they tally with what I have read for merchant types right into the classical era. I think the top one might be a large vessel by contemporary standards and have doubts about decked over holds so early but OK.
In the images at the link the bottom one is a Roman grain ship, much too sophisticated for 1500-1200 BC.
The top one may have the right hull shape but the rigging is too complex, the main mast is too tall and the bowsprit is not evident that early – and ditch the cabin and probably the overall deck … but the hull look OK !!
