Gunports on Dutch warships

From the Van de Velde drawings, we know something about gunports on Dutch ships in the period of 1639 to 1654. The Gorinchem is from a drawing of the ship in 1665. I would welcome corrections, as I am particularly uncertain about the Brederode. The picture of the Rotterdam is in Dr. M.G.de Boer's book, Tromp en de Duinkerkers, opposite page 49. The picture is so indistinct that I can't count ports.

When did the Dutch fire on Deal?

The Dutch seemed to have fired on Deal, sometime during the period of 1639 to 1667. As far as I can tell, there were opportunities during the Battle of the Downs, in 1639, during the fight on 29 May 1652 (new style date) and on 3 July 1652 (old style date). There may have been other possible occasions, but I am not sure about them. Does anyone know?

The Friesland ship Groningen

I was just looking at the page from April 1653 (apparently) that mentions the ship Groningen, of the Admiralty of Friesland, at Sardam, presumably under construction, that would replace the Graaf Willem and Waterhond. The dimensions given, 132ft x 31ft x 14ft x 7ft, are those given in Van Foreest and Weber's book.

Jan van Campen in 1652 and 1653

In 9 June 1652, Jan van Campen was listed as being off Cape St. Vincent in command of the three-masted jacht Windhond. After returning home, he seems to have been responsible for fitting out the new ship Campen (40 guns). By September, he was appointed to command the ship Overijssel (26 guns) that had been commanded by Abraham van der Hulst. Ships and captains were shuffled in August and September 1652. Jan van Campen commanded the Overijssel through the rest of 1652 and 1653.
