A three-masted warship against a sky piled with clouds fills most of the right half of this vertical painting. The cream-white sails are bright in the sunlight, and tiny deckhands work along the horizontal yards and along the rigging. The flat stern faces us and is decorated with a rearing lion and unicorn on either side of a shield among gold molding. Eight hatches along the port side of the ship are lifted, and smoke shoots out of one of the cannons poking through the openings. Six men row a boat carrying seven more men to the left. A large flag fluttering from the stern has a red and white cross on a blue field. A single-masted sailboat with its red sail furled has pulled up to the stern of the warship, and three people work there. Another warship with sails partially raised floats in the hazy background to the left. The horizon comes about a quarter of the way up the composition, and clouds shaded with muted peach and lavender-tinted gray fill the sky along the horizon and break along the top third of the painting. Minuscule in scale, two white and black birds fly low to the water near the lower right corner of the painting. The artist signed and dated the painting as if he had inscribed a piece of driftwood near the birds: “W. V Velde In Londen 1673.”
