Vesuvius Gavriil Kondratenko (1854-1924)

The picture has something of this: water, seashore, sea, landscape, ocean, mountain, island, watercraft, dawn, bay, outdoors, sky, ship, vehicle, sunset, beach, reflection, scenic.
Perhaps it’s a painting of a boat in a body of water with a castle on top of a rock outcropping in the middle of the water.
