The Dutch fleet in early 1652

The Dutch were preparing for war, in early 1652, with just 87 ships, of which 41 were convoyers (largely, the ships funded at the peace in 1648), 36 cruisers funded in 1651, and 10 ships for Brazil. Almost immediately, two Amsterdam ships were sold. These were the Nassau and the Overissel, a veteran of the Battle of the Downs in 1639, and one of the ships sent to Brazil with Witte de With in late 1647. The situation was radically transformed, when on 3 March 1652, the Extraordinary Equipage was enacted, whereby 150 ships were to be hired and fitted for war. These included 50 ships hired by the established city Directors and 100 hired and fitted out by the five admiralties. While the 50 Directors' ships were successfully hired, but only 38 of the planned 100 ships could be initially hired. Sources:
