I really cant remember why this was installed (its not there now).
The photo was taken during construction (about 7 years ago).
I think the original plan was to separately control the jib sail or possibly to animate the figure (Capt Jack Sparrow).
The winch is spring loaded to keep it under tension, this is running inside the tube you can see in pic.
Other changes not in the original pics include installing a gearbox on the motor to step it down.
Photos as it is now attached
