One immediate problem with my list

I realized that I had not considered the Noorderkwartier ships that are known to have been included in the 36 cruisers funded in 1651. They need to be deducted from those that I included for 1648. We are reasonably sure that all forty ships were in service in early 1652, and probably one extra ship, as Dr. Elias mentions 41 ships. There were also the 36 cruisers funded in 1651 and the ten ships sent to Brazil, which returned by June 1652, when some were lost.
