An English Flagship Under Easy Sail in a Moderate Breeze Charles Brooking (1723-1759)

The picture has something of this: watercraft, ship, sailboat, transportation system, sea, water, sail, ocean, boat, vehicle, navy, wind, storm, warship, light.
Perhaps it’s a painting of a group of ships in a body of water with a cloudy sky in the background and a flag on a pole in the foreground.
