Bakhuysen, Ludolf – Het IJ voor Amsterdam, van de Mosselsteiger gezien, 1673 Rijksmuseum: part 1

The picture has something of this: watercraft, sailboat, ship, transportation system, people, vehicle, group, harbor, water, sail, sea, boat, merchant, many, navy, ocean, fishing boat, boatman, warship.
Perhaps it’s a painting of a group of people on a dock next to a body of water with boats in the water and onlookers in the background.
