The Jackson Kayak Gnarvana Whitewater Kayak! Designed to run rivers and creeks quickly, the Gnarvana is nimble, sporty and fun. This boat is the combination of the friendliness of the Nirvana and 10 years of creeking experience, made to bring boaters to new heights. With more bow and stern rocker than the Nirvana, this boat is arguably unpluggable. It is the easiest boat to boof, maneuver and paddle. You can expect to have a dry ride through even the hardest whitewater. The improved hull has a full drop down chine making carving a breeze. Now available in 3 sizes!
