Need help loading a canoe onto a car

[smartino]

Is there some sort of rig out there that would allow one person to load a canoe onto a car rack? I have a 17ft aluminum canoe and was hoping to be able to load and unload it by myself. I picture some sort of wheels or rollers-- can you help a sister out?

Yakima makes a product called the Hullyrollers that allows you to roll your canoe onto the top of your car. I also saw something from them a few years ago that allowed you to extend the Yakima bars outward for easier loading of large boats. Hope that helps.
