Two very similar ships: the Hollandia and the Amsterdam

In 1652 and up to March 1653, Albert Claesz Graeff commanded the Amsterdam hired ship Hollandia. This was a ship with dimensions of 130ft x 29ft x 13ft. The ship carried 18-12pdr, 14-6pdr, and 2-4pdr guns in 1652. I realized the Sijmon van der Aeck's ship, the Amsterdam hired ship named Amsterdam was very similar. The dimensions were the same: 130ft x 29ft x 13ft. The Amsterdam was armed differently, however: 10-12pdr, 8-8pdr, 8-6pdr, and 4-3pdr guns. The Hollandia seems to have been discarded after the Three Days Battle (the Battle of Portland). The Amsterdam served up to at least November 1653, although a different captain was in command after April 1653, Paulus Egbertsz Sonck. The Amsterdam was with Witte de With on the voyage to Norway from September to November 1653. These were originally both nominally 30 gun ships with a crew of 100 to 120 men.
