English measurements: Length on the keel: 84ft Beam outside of the planking: 25.5ft Depth in hold at the center: 9.67ft Estimated Dutch Dimensions in Amsterdam feet (283mm): Length from stem to sternpost: 112ft Beam inside the planking: 29ft Hold at the side: 11ftI have seen estimates that there were as many as 15 ships in the fishery protection squadron in Dr. Elias's book, Schetsen uit de Geschiedenis van ons Zeewezen, Vol.II. We know the identities of 13 of these ships, although fewer of the captains. I have wondered if another Dutch prize used by the English, the Sophia, taken in 1652, might have been an otherwise unknown member of the fishery protection squadron. The Sophia's dimensions and estimates are as follows:
English measurements: Length on the keel: 90ft Beam outside of the planking: 26ft Depth in hold at the center: 11ft Estimated Dutch Dimensions in Amsterdam feet (283mm): Length from stem to sternpost: 120ft Beam inside the planking: 29.5ft Hold at the side: 12.5ftThe Sophia seems to be too large, though, to have been relegated to the fishery protection squadron. She carried as many as 34 guns in the English service. Her other name was Speaker's Prize. The only question is where she came from. My own parochial view of the Battle of the Kentish Knock is that the only two Dutch losses were the Maria (Claes Sael's ship) taken as prize and the Burgh van Alkmaar (Gerrit Nobel's ship), which was destroyed by explosion. Perhaps the "Sophia" (we don't know her Dutch name) was a merchant prize that was good enough to be taken into the English naval service.
