On a wide, calm sea are six warships. The sails are hoisted, lifted the anchors. The mirror of the vessel on the right is decorated on the front with the arms of Amsterdam, held up by two standing lions. Probably, these are part of a war fleet is preparing for departure. A sloop with distinguished figures, probably of the Admiralty, flying and trumpets salutes along the vessels, while just down the final provisions and crew are taken on board. What is striking is the tremendous accuracy in the reproduction of details: rigging, sails and cannons.
