Seventeenth-century Dutch ship design drawings. Real or counterfeit?

摘要

All in all, the conclusion seems inevitable to me: the series of pinas drawings is completely unreliable as a historical source for shipbuilding in Holland and for the pinas as a ship type. The statenjacht drawings and the section of the warship belong to the same group and are anachronisms. The state of the art in Storck's days was at a different level than presented here. The first Dutch design drawings showing folded frames in a side view date from almost half a century after the date applied to the statenjacht drawing. They were not made by an outsider such as Storck, but by the Zaanse shipbuilding master Gerbrandt Slegt, who worked for the Amsterdam Admiralty yard from 1723 to 1726.
