In a note on page 91 of Dr. Elias' book, Vlootbouw in Nederland, there are some figures that I had not noticed, before (ship dimensions). This is what it says (my translation):
The largest of these ships, namely the Archangel Michael (that in the war service was used as a transport), of 143ft length and 32-3/4ft beam and armed with 46 guns, was a fluit.
Both of the other largest charters, namely, the St. Matheeus, of 144ft length and 36ft beam, with 50 guns, and the Groote Vergulden Fortuyn, of 141ft length and 31-1/2ft beam, with 46 guns, were hired by the Directors of Amsterdam and used as warships.
There is nothing here that I had not seen in some form, elsewhere, but it could have been something I could have used prior to obtaining the archival documents about Amsterdam Directors' ships.
My armament information for the Groote Vergulde Fortuyn differs from that given here. This was the ship commanded by Frederick de Coninck for the entire First Anglo-Dutch War. The figures that I have for 27 March 1652 and 8 November 1652 for the armament are for a 35-gun armament with 4-brass 24pdr of the state, 16-12pdr, 11-6pdr, and 4-3pdr. This agrees with the figures given in The First Dutch War (from the Hollandsche Mercurius) and in Hendrik de Raedt's pamphlet. I would not be surprised if the ship could have been uparmed to 46 guns, given the size. There are many examples of armaments being increased in the war (the Vlissingen Directors' ship Witte Lam and Pieter Florissen's ship Monnikendam to name just a few).
