The Special Sail Rig fits better quality inflatable kayaks that have enough rigidity and enough attachment points. This video shows the steps from in-a-bag to on-the-water. Assembly is quick and easy. No tools! Among the kayaks that work with the SailboatsToGo Special Kayak Sail Rig are the Saturn Expedition models, and most Aire models, including the Tomcat. http://www.sailboatsToGo.com
