Transporting a sit on top kayak can be quite challenging due to the large width and often the heavier weight of these watercraft. The Sit on Top Cart is a unique kayak cart that is universal in application and robust enough to cater to a large range of sit on top kayaks. Features include tapered cones that fit snugly into a broad range of scupper hole sizes while also reducing side-to-side movement of your cart during towing. Furthermore, Sea to Summit has added a variable width axle design with a heavy duty quick release clamp that will fit most recreational sit-on-tops.
