The image shows a yellow sign with the text "6 Knots Max" written on it. The sign is located on the side of a riverbank, with a stone wall on the right side. The wall appears to be old and weathered, with patches of grass and shrubs growing on it, and there are trees and bushes in the background. The riverbank is muddy and there is a small bird perched on the edge of the water. The sky is overcast and the overall mood of the image is gloomy.
