Friedrich, Caspar David. Sailing Hermitage ~ part 12

The picture has something of this: watercraft, sail, ship, sailboat, transportation system, rope, boat, people, vehicle, nautical, yacht, schooner, ocean, regatta, vintage, ocean cruise, mast, boatman, sea.
Perhaps it’s a painting of a man and a woman sitting on a sailboat in the middle of a large body of water with a sky in the background.
