A long, red and blue narrowboat, named "MARSDEN" on its bow, glides along a sun-dappled canal or river. Several people are visible on the boat, seated and standing, appearing to enjoy the ride. The water shimmers brightly under what appears to be a clear, sunny sky. Lush green trees and foliage line the banks of the waterway on the left side of the frame. The boat moves steadily from the right side of the screen towards the left. The scene suggests a pleasant daytime journey on a waterway in London.
