This picture was taken from HMS Skiddaw and shows another loaded paddle steamer full with troops. This picture too is from a sequence which includes shots of Dunkirk and is most likely to show the vessel returning with men rescued during the evacuation. I cannot identify this boat. Can anyone help? Unfortunately it appears that a side rail from Skiddaw is obscuring part of the image.
Pete the Paddler and Phil Trigg both agree the boat is PS Glen Avon.
