Well designed and built. As described: easy assembly, sturdy, and good videos to explain the different configurations. The cart is supporting a 25 foot Liteboat that weighs 150 pounds. When rowing and voyaging, the cart sits upside down and fully assembled at the stern. The cart floats which makes attachment to the row boat at the beach straightforward. Excellent work Suspenz! Thank you.

This kayak cart/trolley great. Fits the bottom grooves of my kayaks and maneuvers great on the ground surfaces I pull mine on.

Easy to put together.

I bought this for less common use case of transporting an OC1 and OC2 canoe about 4 blocks to the water. I could not find much information online about what carts would work well for that. Also the walk to the water is mostly pavement but also includes some rutted mud as well as grass, dirt, and sand. The no-air bicycle tires are perfect for pavement and they work well on dirt, grass, and sand. They are (as expected) not fantastic for soft sand but work well enough for a short distance. I can easily get the canoes on and off the cart. I position it rudder-down (toward the street) and with the rudder toward the back, where I push from. I position the cart just slightly to the stern of center so that the bow will naturally fall. This way I can be sure the rudder doesn't hit the ground. To go over curbs and bigger bumps I just have the other paddler pick up the bow, or if I'm alone push it gently up.

Review for Catch Mode owners!

This is my fourth cart (3 companies) trying to set up a functional cart trolley for my Pelican Catch Mode 110. As owners may know, the Catch Mode series has a "tunnel" hull configuration. This means that fitting a cart to a completely loaded fishing Catch Mode is challenging to say the least.
Note: this cart has two configurations. This review is for the parallel mode and not the "cross" perpendicular mode.
First determine the distance to set the bunker bars apart to align just into the edges of the "tunnel" (it's abourt 9.5 inches if memory serves). It's best to flip over your yak to do this.
Now here is the key:
Forget using the Suspenz straps in the way the instructions state.
The reason is two-fold;
A) The design of the "straps-through-the-bars" is a big pain in the you-know-where to adjust the fastening design above the gunnels. I feel this strap/bar arrangement was designed more for perpendicular crossbar use.
B) More importantly, and crucial, is because the Catch Mode is a tunnel hull design, pulling the cart up into the hull snuggly is impossible with the through the bars straps. It won't happen, because you are pulling the bunker bars laterally "apart" left and right, and not vertically into the tunnel hull.
The answer is to attach the two straps TO THE AXLE of the cart between the bracket mounts. This way, the straps, when pulled up above the yak the cart are vertically snugged into the tunnel hull corners. IT WORKS BETTER FOR THE CATCH MODE.
I had long phone conversations, with Spuspenz customer rep, Laurie, to let her know my findings and she was a supremely helpful and listened to my findings, as well as other cart points unrelated to this discussion.
