In the 1970's Tim Niemier began building sit-on-top kayaks in Malibu, CA. In the 1980's he started a revolution with his Scupper line of plastic kayaks. Over the next few decades these kayaks reigned supreme. Until now. The Swell Watercraft 14 and 16 have pushed the limits again. Patented one way scupper valves allow for a complete overhaul of the traditional sit on top kayak. A lower center of gravity allows for a sleeker, faster design without sacrificing stability.
