I kitted Gilli T a couple of years back. Was around September. The current between the islands generated by the tide is so strong there is pretty much standing waves. If you loose your board you won't get back to it. A friend and I shared a kite so the other could get a boat to rescue the gear if required, which we needed once. There was only one other guy that kited Gilli T while I was there and that was a French guy that worked at the dive shop , and he lost his board not to be found due to the current.
But was awesome kiting still.
