I am researching the history of the Rixen Cable WaterSki park on Jekyll Island for a video on "Hidden Jekyll".
When I first came to Jekyll in the late 1980's, the Rixen (tm) system was in place, but it looked abandoned or not used very much. The park was near the present-day water park (slides and such) and was in a large rectangular pond, presumably dug out for such a purpose.
In the early 1990's, as I recall, the hardware (cables, tow lines, pulleys, etc.) disappeared, leaving only the towers in place. I believe they too, are now gone.
The Jekyll Island Authority has made Ski Rixen Pond (it is still called that) into a salt water fishing site, with two new floating docks and other facilities for those who want to salt water fish, but don't own a boat.
The ski building is now a kayak and nature center.
I will try to post a video on YouTube later this year, showing the site.
So, sorry, as far as I know there WAS a Rixen-system cable park on Jekyll Island, but I know of no plans to re-install it. Given the investment made to make the existing pond into a fishing site, it seems unlikely they will bring the Rixen system back to Jekyll anytime soon.
The island is undergoing a lot of renovations, including miles of bike trails around the island and through the maritime forest. See; http://www.youtube.com/watch?v=a4zJ3DihBL4
It seems the Authority is going for more of an Eco-friendly sort of theme on the island, and I am not sure cable-waterskiing fits into this, at the present time.
That's a shame, as it would attract a younger crowd to the island, too.
