A question: is this ship Hoorn the ship commanded by Pieter Allertszoon up to the Three Days Battle?

We believe that Pieter Allertszoon commanded the ship Hoorn (or Eenhoorn) from sometime in 1652 up to the time when he was killed in the Three Days Battle on 28 February 1653. Ron van Maanen has the details of what seems to be that ships. The dimensions were 120ft x 27ft x 11ft, with a height between decks of 7ft. The armament was 6-12pdr, 20-8pdr, 4-6pdr, and 2-4pdr guns (a total of 32 guns). Sources:
