I'd have to dig for it, but there was an actual example of using the propeller thrust of decked aircraft to help dock an aircraft carrier.
Not by blowing against the ship's superstructure (the "island"), but by the planes' collected thrust as they were anchored to the decking.
Maybe it was just to hold the ship's position against the tide or something.
I think I saw this in Jablonski's "Airwar" series, but I'm not sure.
