The Biyak features a patent pending design that makes it one of the most versatile small boats in world. While catamaran designs are recognized for superior stability, the Biyak goes a step further. It offers a variable beam that can be adjusted by an operator on the water. Simply loosen the tension knob and push outward on the pontoon handles to expand the boat from a paddling width of 30” to a super-stable width of around 48”. In its narrow configuration the Biyak behaves like a sit-on-top kayak. It’s quick and it tracks exceptionally well. Open it up and the Biyak is perfect for stand-up fishing, or sail it with an optional sail rig. The Biyak easily breaks down into three pieces, so a single person can secure it to a car top.
