A person is seen cleaning the green deck of a vessel, likely a ship or ferry, with a hose and a long-handled brush or squeegee. They are wearing dark clothing, including a jacket and trousers. Water is actively being sprayed and pushed across the deck, creating splashes. The scene is set on the open water under a clear blue sky with a few scattered clouds. The sun is bright, reflecting strongly off the blue surface of the water, indicating daytime. In the background, the vast expanse of water meets the horizon. White railings and other ship structures are visible, framing the deck area where the activity takes place. There are no specific geographical landmarks or discernible text in the video. The person appears focused on their cleaning task.
