After numerous requests to build an inflatable kayak (IK), we spent the 1994 season testing designs for a high performance IK. In 1995 we produced, on a limited basis, our SOTAK. Since 1996 we have offered a high performance kayak with the features you want. All SOTAR Inflatable Kayaks come standard with an adjustable inflatable seat, footbraces, thigh straps, and an inflatable I-beam floor.
