The plan for Dutch ships in 1652

When described in books, the Dutch plans for equipping the navy with ships in 1652 seem to be very well-defined. There were the 40 convoyers authorized in 1648, the 36 cruisers authorized in 1651, the 50 Directors' ships and the 100 ships, both authorized in 1652. The reality was that the plan was less certain then what was published. There may only have been 36 of the 40 still in service by May 1652, for example. As for the 100 ships, there were never that many ships hired or activated from the reserve.
