🏆 Paddling Magazine — Best Whitewater SUP 2026"Riding the Hala Atcha 86 is like dropping into the river on a skateboard."Read the full Paddling Magazine review → The River Surf & Whitewater Party Machine. The Atcha 86's 8'6″ × 34″ shape is built for paddlers who live to surf river waves and throw technical moves on Class II–IV whitewater. Want to lock into a standing wave and carve until your legs give out? This is your board. Nimbler than the Atcha 96, with the same patented StompBox 2.5 retractable fin system and full-board rocker that has made the Atcha series the gold standard for river surfing on an inflatable SUP. The 2025 version raises the bar: an updated rocker profile makes it easier to park on a surf wave and stay there, a redesigned pointed nose climbs over river features instead of slamming into them, and refined fin placement improves both downriver speed and surf hold. Stable up to 250 lbs, built to reward aggressive surfing and paddling at any weight. Hala's patented StompBox 2.5 retractable fin stays spring-loaded at full depth — zero bounce, zero catching on rocks. It deflects automatically and springs back before your next stroke, giving you locked-in drive through technical lines and real surf hold on a standing wave. Two removable 4.5″ gummy side-bite click fins are included. Fin options and board comparisons are below.
