Kayak Carriers

[amishco]

So not meaning to sound to dumb here, and being new to this forum my question is this...

I have a Thule roof rack with teleport kayak carriers that I can put on my truck to carry my yaks. The question is aerodynamics while towing my ST29BH and using these roof racks for the yaks, will I end up with to much drag hitting the trailer? has anyone used this system of transporting their yaks before?

You may not believe this but I was told that they will help with milage buy breaking up the air flow. I will find out this winer when we take our canoe to fl. from NY.

They should not add to the drag unless you carry them sideways.
