The C-Tug Double Hauler with Sandtrakz Utilizes two RAILBLAZA C-Tug Sandtrakz Carts along with a double up bar. The Double Up Bar allows you to assemble 2 x C-Tugs together, spreading the load and allowing you to carry heavier kayaks or boats. The bar is a specific length to keep the wheels close together allowing the double cart to be turned easily. Once loaded and balanced no lifting is required, all you have to do is pull it. The Sandtrackz Wheels are perfect for moving loads over soft sand, wider wheels are not necessarily better. Bulldozers and military tanks use long tracks, reducing the chance of them digging in. SandTrakz puncture free wheels mimic this track system, the outer rim compresses when in use giving a longer track length. On soft sand this reduces how hard you have to pull to move your trolley by more than half compared to standard puncture free Kiwi Wheels! An absolutely essential cart for your vessel that is loaded down with accessories and heavy fishing gear.
