This is a scupper cart. It is a set of wheels that fits in the scupper holes of the kayak and lets one person wheel it around like a wagon. The big advantage of this sort of cart is that when you get to the water, you can pull it out, flip it over, and stick it in the top of the kayak. Then off you go – no need to double back to put the cart away. Also, you’ll have it if you get somewhere that you might want to portage.
