Ron van Maanen has as many details for the ship
Groote Alexander, which was hired in 1639, as he has for ships that served in the First Anglo-Dutch War. He speculates that this ship might have been the Spanish
El Gran Alejandro taken in 1639 (at the Battle of the Downs?). Ron says that in 1639, the ship was five years old. These are the details:
