The Original River Surf & Whitewater SUP. Since 2013, the Atcha 96's 9'6″ × 36″ shape has defined what an inflatable SUP can do: surfing standing waves, locking into river surf spots, and charging Class II–IV whitewater. It's the template every competitor eventually adopted, built through 50+ prototypes. Independent reviewers now call it "quite possibly the pinnacle of design for intense whitewater paddling" (Inflatable Boarder, 2025). The 2025 version is the sharpest yet. Refined rocker climbs high over wave trains and holes, a redesigned pointed nose punches through steep faces instead of slamming into them, and full-board rocker delivers true surfability — park it on a river wave and carve, or use it to blast downriver through technical Class IV lines. Hala's patented StompBox 2.5 retractable fin stays spring-loaded at full depth — no bounce, no catching on rocks. It deflects automatically and springs back before your next stroke, giving you consistent drive, locked-in ferry angles, and real surf hold on a standing wave. Two removable 4.5″ gummy side-bite click fins are included. Rated for 325+ lbs of paddler and gear. Fin options and board comparisons are detailed below.
