The image shows a harbor with water and boats extending towards the distance. The horizon line is above the midpoint, with silhouettes of windmills visible against the skyline. The sky is covered with textured clouds. The brushstrokes are rough and sketchy, creating movement and texture. The color palette is monochromatic, with dark shades and lighter tones. Closest are indistinct, large objects that appear to be ropes or bundles, and a cask in the lower left corner. In the distance, figures and boats are seen on the water, merging into the shadows. The forest of sails from docked boats and distant buildings merge into the horizon, framing the windmills.
