Have kited the area quite a bit over the last few years. Strongly recommend getting a boat and be very aware of the tides and the currents as they can exceed 7 knots.
The wind can be extremely consistent from sunrise to sunset and Ive had some epic all day flat water sessions.
Without giving too much away I think you'll be amazed at the variety and potential

As for never seeing a kitesurfer, I know a bloke that was photographed kiting on the front page of the Torres News.......
