If you have the type of kayak rack that sits on top of your vehicle in the shape of 2 "V"s, you can replace the rear "V" with a roller...it sits at the very rear of your vehicle at the base of that "V". I have on on my vehicle and it has been a tremendous help in my being able to load and unload the kayak without assistance. I don't know what you drive but I have a very tall Ford Explorer Sport. When I load the kayak, I stand it up, lean the tip into the V and lift from the rear of the boat. By the time the boat is halfway on, the remainder of the boat is completely over my head, arms extended up all the way. The roller takes some of the weight off and eases the pushing. I had my rack on the Explorer all winter and it still works like a charm!
Ok...enough of the plug for Thule, I'm off to load up the yak for some later afternoon paddling.
