On the tafferel are the arms of the province of Groningen, supported by two lions. On the rail above is a full-length figure with dolphins on either side.

There were three ‘Groningens’ in existence in 1665-6. The first was built in 1641, by the Admiralty of Amsterdam, and chartered by Denmark in 1666-7. This ship is well shown in a grisaille at Greenwich. The second was built in circa 1658 by the Admiralty of Friesland, and was captured by the English in 1665. This ship was called ‘Black Spreadeagle’ under the English and probably had only a large eagle displayed on the tafferel, which are the arms of the town of Groningen. The third was built circa 1666 by Admiralty of Friesland.

This is an unsigned drawing by the Younger in a light and uncertain pencil, which according to Robinson, is suggestive of an earlier period than 1666, but the watermarks and subjects confirm the date.
