Zeeland ships

I was interested to see that Leendert den Haan's ship, the Haes in 't Velt, which was 116ft long, had a "main battery" of 14-6pdr guns, while Bastiaen Centsen's ship, the Haes, which was 113ft long, carried 4-18pdr guns, as well as smaller (mostly 8pdr and 6pdr guns). I would think that the Haes in 't Velt was underarmed.
