I too just recenty purchased a C-Tug cart. I got tired of having to unload my revolution kayak to flip it on its side to insert the scupper hole cart. When Kayak fishing I have a crate mate and/or live bait tank up to 4 fishing rods, and a cooler in the well of my revolution. When I have a long portage back to my vehicle it sucks to have to unload everything, flip kayak, put in the scupper cart (unless I have someone there to lift the back of the loaded kayak up high enough to get the scupper cart in), then load it back up to haul to my truck and then unload again. Now I just put the cart alongside the kayak lift it onto the cart strap it down and off I go. The adjustable support plates even make it possible to place it under the bow and push your yak out of the water from the rear. They also now have sand wheels for $24.50 ea. Now you can have a pneumatic tires and sand wheels in one cart. Great cart & excellent Customer Service.
