Hello Johan. In his book "Het Schip van Barentsz", Ab says:
Al eerder is opgemerkte dat op de platen van De Veer over het algemeen zeven geschutspoorten per scheepszijde te zien zijn." / It has already been noted that the plates of De Veer generally show seven gun ports per ship's side."

Five gunports are visible (the fifth one is largely invisible but if you look closely, you can see the open gun port lid where the anchor hangs.) There is a strong possibility of a sixth at the bow, but it is not conclusive.

Six gunports are visible. It is possible that there may have been a seventh port right at the bow, but you cannot see it.

Five gunports with a suggestion that there may be a sixth at the bow, but you cannot see it.

Five gunports are visible. Their positioning would suggest that there would have been a sixth port towards the stern, but it is not shown.

A very definite five gunports are shown.

Six gunports are visible with a very strong suggestion of a seventh at the bow. This is the picture that comes the closest to showing seven.
View attachment 325074
Only four gunports are shown.
Therefore, I cannot agree with Ab's surmise that De Veer's drawings consistently show seven gunports. Thus, the drawings are most certainly not scientific proof by any means.
My decision is again based on the information that I have of De Zwaan.

Inventory issued by the Equipment and Ammunition Master of Veere, Pieter Reygersberg, 1595.
English Translation: From the magazines of the Admiralty (Zeeland) De Zwaan will be equipped with two bronze cannons of 8 pounds each and two bronze cannons of 1-pound each. The rest of the artillery inventory is as follows: 6 Gotelingen* (Cast Iron cannons) and two Steenstukken (Rear Loaders). From the cannon balls found in Het Behouden Huys, we know that the gotelingen were either 2- or 3-pounders, or both.
This results in a total of 12 cannons (including the two steenstukken). Six gunports per side would certainly have made sense.
