Yesterday CNET posted a mini gallery of somebody who transformed their canoe into one of the greatest boats on this Class-M planet we call earth.
This was put together for the annual Venice Canals Association holiday boat parade and of course it won first place. Captain Kirk would have had it no other way.

Check out this old photo of a motorcycle sidecar with a quick-detachable canoe. I can’t believe that the side car was an actual commercial item available in 1927-1927.
You can see more unusual canoe sidecars on the always entertaining Paddle Making blog.
I don't know what I would do if this happened to me. Imagine you park and quickly run into the corner store to grab a few things for home only to discover when you come out, the there is now a canoe sitting on top of your car.
Actually, thinking about it, I think that I would enjoy it...
How long is a long kayak? How wide is a wide kayak? How fast is a fast one? Who cares?
