Stacked canoes-better solution!

I also drove long distances with stacked canoes on top using too narrow bars (you could buy longer bars if the rack permits it). I damaged a lapstrake wood canoe (my favorite) doing just that . In my anger at my stupidity, I came up with a better solution and have used it successfully a number of times. It works with Yakima and Thule square bars-will be interesting to see if I can adapt it to the Thule aero bars on my new car.
Buy two straight 2"x3" and cut them to the length that you need to situate the two canoes on their gunnels. Place the 2"x3" on top of your bars and attach them with long hose clamps (like radiator clamps but longer) around the 2"x3" and your bar. I also did some redundant lashing with parachute cord by the hose clamps as safety back-up. Have made many 7 hour rides with that set up. The radiator clamps have held every time.
Cheap and proven effective. I bought the extra long hose clamps at a auto parts store.
