C4 Rapid Rider is the stand-up paddleboard that doesn’t need to run from the gnarliest whitewater rapids. This military-grade inflatable SUP is the result of four years of intensive R & D by C4 Waterman’s crack team of river-to-sea experts. nothing alarms the unique triangular plan shape and double-X width of the C4 Rapid Rider. The unique shape allows the paddler the ultimate in stability, coupled with amazing turn and spin dexterity at low planing speeds in even the trickiest currents. This board can crank a full 360 whip turn twice as fast as any conventional SUP paddleboard. The incredible stability and snappy turn rate makes this board a terrific fitness or cruiser vehicle for novices. Included: Bungee attachment points, FCS fins, deck pad, pump, repair kit, travel bag and board strap.

Intermediate to advanced. Under 220 lbs.

All C4 iWATERMAN products are fabricated from heavy-duty, military-grade, double-wall PVC material. Inside each product, thousands of high-tech fiber ‘cilia’ anchor the deck to bottom, allowing for superior rigidity and locking in C4’s proprietary rockers–features that grant never before seen durability and the closest thing to hard board performance of any inflatable surfcraft. And unlike the other brands that use only glue on their seams, the iWATERMAN products are finely stitched with 30% additional thicker, high-tensile fiber thread, making them much tougher, stiffer, and able to withstand a higher PSI (pounds per square inch) of inflation, ranging from 14 -17 PSI. The result: A rough-and-ready surf/paddle/rescue tool that is pliant enough to bounce off rocks, yet still deliver hard product performance and reliability.
