The Skylon is one of the original extensions for your pylon if you have a tournement style inboard. Tried and proven for many years. There are other brands out there but they all basically allow you to get the tow point for the rope higher. Towers do the same with more structure and also allow for more accessories and keep the interior of the boat more open. Look online, Overtons, Barts etc and see what you like and go from there.
