man walking on a wooden dock in a marina. He is carrying an orange canister in his right hand and what appears to be a black tube or hose in his left hand. He is wearing a black shirt, dark pants, and a cap. The marina is filled with various boats, including sailboats and motorboats, many of which are covered with white protective tarps. A multi-level building with a visible terrace is in the background. Another man is visible standing on the dock behind the first man, possibly working on a boat. The sky is clear and blue.
