Works very well. But you need to determine a few things. First, when you lean the kayak against it, what will prevent the kayak from rolling back? And what will protect the rudder from bending or rubbing against the road? Secondly, how will you cart attach or detach while you load? Thirdly, will the roller apply pressure to the transducer at the bottom of the kayak? And finally, is it safe to transport your kayak facing up?For me, with the Hobie Outback Mirage 2020, this was pretty easy. Plug the cart, plug the load assist (included with the Hobie), position the kayak, and lift the front to the roller. Then lift the back; the cart automatically detaches. Now push the kayak into position. Thankfully the antenna doesn’t snag while doing so, and the kayak makes contact with the cross bars. To offload, repeat in reverse.Edit: I’ve been using this device every trip, to load and unload. Had at least 20 trips. And also tried it with another Hobie kayak (Revo 16). Again, works great and is light weight. However, I had two accidents: on one occasion it was dark and I didn’t see that the kayak was slightly off center. It slid to the side, dented the car parked next to me, and fell on the road. On another occasion, while pushing the kayak up, when the transducer recess hit the foam roller, instead of lifting the kayak up and continue pushing using only the cross bars, I kept pushing the kayak on the roller. The roller detached and scratched the trunk. It also hit the glass, which thankfully didn’t break. Both accidents are half my fault. Loading a 100lb kayak on a car can cause serious injury to people and property. The manufacturer should warn users.
