Boonedox has some great accessories and add-ons for a wide range of kayaks. This is their version of the Hobie scupper cart, with a few advantages you might like. The uprights are taller, allowing greater separation between the bottom of the hull and the wheels. Also the CTug-style wheels are wider than most models in this price range, which makes them better on sand while still mostly indestcutible on hard surfaces. Lastly, you will note the structure and welds are more robust than some competitive models.
Fits most any rigid Hobie kayak with standard scuppers.
