In 1628 and 1629, Cornelis Engelen Silvergieter commanded the Rotterdam ship
Zeekalf. The
Zeekalf was a vessel of 170 lasts built in 1623. She had a crew of 85 men and carried 23 guns. Her armament consisted of 2-18pdr, 2-12pdr, 14-8pdr, 1-6pdr, 2-5pdr, and 2-4pdr guns. We are fortunate that this level of detail is available for ships as old as this (at least from the Admiralities of Rotterdam and Amsterdam).
