I have a document showing the employment of Amsterdam ships in home waters on 29 July 1652. The list shows that the following ships were convoying the fishing busses in July 1652 prior to the English attack on 22 July:

the ship Engel          kapitein Maerten Schaeff     28 guns and a crew of 80 men
the ship Marcus Curtius kapitein Hendrick Kroeger    24 guns and a crew of 70 men
the ship Patientia      kapitein Adriaen van Loenen  24 guns and a crew of 70 men
the ship Catharina      kapitein Dirck Bogaert       24 guns and a crew of 70 men
