A hired ship fighting in the Battle of Livorno on 15 March 1653

We don't know which ship this was, but it was almost certainly one of the ships hired by the Admiralty of Amsterdam in Italian ports. All of these ships carried 28 guns and had a crew (at least nominally) of 100 men. The ships were rather large, being 128 to 140 feet long (Amsterdam feet).
