'As whitewater SUP continues to evolve, people are looking for more agile shapes,' said Hala Gear President Peter Hall, whos new Hala Atcha 86 measures 8 feet, 6 inches-by-34 inches-by 6-inches and comes with a generous rocker and whitewater-surf shape. That includes a wide nose narrowing into a shallow tail for stomping Class I-III rivers. Also look for the Atcha's new drop-fin — a spring loaded fin that collapses when hit by a rock, meaning no more playing Superman.
