It’s a freakin’ Transformer! Three hydraulic jacks tension the 16-foot, 48-pound kayak’s skin until it’s absolutely solid. Headed across the bay? Loosen the center jack so the hull lies flat for maximum speed and stability. Need maneuverability? Increase the tension so the boat bows up at the ends. You can even make the craft bend into a right- or left-facing crescent to combat crosswinds.
