Bonnlo Foldable Kayak Cart with Airless Tires - Heavy Duty Canoe Dolly for Fishing Kayaks, Paddle Boards & Boat Transport - Includes 2 Ratchet Straps (Perfect for Beach, Lake & Outdoor Water Sports)

These work great. I had some others before, similar but not the same. My old ones had no straps, so I used one rope for the front support and a 2nd rope to keep the kayak from pulling forward off the cart. The 2nd rope was very important. It was tied to the front hole of the kayak where the handle was attached. It went from that point along the top of the kayak to and tied to the rope holding the cart on. This 2nd rope made it impossible for the rope holding the cart on the kayak to slip back toward the end of kayak-thus, keeping the kayak from pulling forward off the cart. The other thing was I did was to put the cart on with a specific support in front-this kept the cart from collapsing as long as I pulled the kayak/cart forward (and made a second circumference rope not necessary. The tires of the cart went flat (the carts were 9 years old). Replacement wheels were expensive so I bought this one (three of them).These carts are very good. The construction is sturdy and they roll nicely. Wheels will not go flat. The two straps work well and make it unlikely the carts will collapse. The straps are fairly easy to put on but a little tricky to loosen (read the instructions). I still use the "2nd" rope and still put them on "directionally" so they cannot collapse when pulled forward as opposed to reverse. Three of us used these on a 1.8 mile trail. They will fall over if you go over a log, root or rock on one side and don't pay attention-but look at what you are doing and you will realize they make it sooo much easier to do a "carry". They do lie flat and can be put on your kayak mount-though I have not done that as we took ours to a lake from the road. If you center the cart well you could easily stow some gear in the kayak (camping/fishing gear?). I am very please with these carts.
