The Bicentennial First Fleet arriving at Botany Bay January 1988 J Steven Dews

The picture has something of this: ship, boat, watercraft, sea, sail, sailboat, transportation system, water, ocean, regatta, nautical, ocean cruise, mast, rig, harbor, navy, wind, yacht.
Perhaps it’s a painting of a fleet of ships in a body of water with a blue sky in the background and a few clouds in the sky above the water.
