Today, I received my copy of De Sleutels van de Sont (UPDATED)

I received a book today that I had purchased from Charbo's Antiquariaat. The name is De Sleutels van de Sont, by G.W. Kernkamp. Mr. Carl Stapel had recommended the book to me. The book has some good material, such as the list of ships, guns, crew, and captains for Witte de With's fleet that convoyed 300 merchant ships into the Sound without paying the toll in 1645. I immediately noticed that several of the captains commanded the same ships during the First Anglo-Dutch War. That led me to wonder if the ship commanded by Gijsbert Malcontent was the same as what he commanded in 1652. In 1645, he commanded the Getrouwen Harder (34 guns and a crew of 100 men). The Getrouwen Harder was a ship of the Enkhuizen Directors. In 1652, he still commanded a ship of the Enkhuizen Directors, although the armament was given as 28 guns and a crew of 110 men. Another captain was Jan Pieterszoon Houck, who commanded a Directors ship of Hoorn, the Swarten Beer (24 guns and a crew of 81 men). In 1652, he also commanded a Hoorn Director's ship, this listed as having 30 guns and a crew of 110 men. In both 1645 and 1652, Gabriel Antheunissen commanded the Medemblik (or Kasteel van Medemblik) (26 guns and a crew of 80 men). Another was Jan Warnaertszoon Capelman, who commanded the Wapen van Alkmaar (or Alkmaar) in both 1645 and 1652. Given that, we might ask if Arent Dirckszoon commanded the Monnick in 1645, as he did in 1652? We also know that Adries Douweszoon Pascaert commanded the Harlingen Director's ship Prins Willem (28 gunsand a crew of 90 men) in both 1645 and 1652. This is really interesting material, if you are into this sort of thing.
