Ron van Maanen has information about an Eendracht built in 1638 and possibly only in service until 1641. The ship was 150 lasts, which could be a ship 116ft x 26-1/2ft x 10ft (Noorderkwartier dimensions for a 116ft ship). Ron has the armament for the Eenhoorn, which was 26 guns: 21-8pdr, 3-6pdr, 1-5pdr, and 1-2pdr.
