Boats in the Port of Le Havre Claude Oscar Monet (1840-1926)

The picture has something of this: watercraft, ship, sailboat, transportation system, sail, water, vehicle, sea, boat, ocean, navy, shipwreck, nautical, exploration, frigate.
Perhaps it’s a painting of a group of sailboats on a body of water with buildings in the background and a blue flag on top of the sailboat.
