winkosmosis,no doubt,the boat will cause some interference over the roof.I do believe such a "roof rack" would however offer the minimum loss do to ,as you've mentioned,the narrow profile with very small frontal area,and drag coefficient on the order of Cd0.06.----------- The majority of the hull should see no separated flow for the entire length.------ Should the kayak be mounted on an inverted aerodynamic pylon as bombs and drop-tanks and bellytanks are done,there would be virtually no drag to speak of.No separation anyhow.---------- Some of my neighbors report that they lose "nothing" when they transport canoe and kayak on their roof.Some have actually claimed "gains."--------- I'm polite enough not to challenge their claims,and one day will test for myself,as I have both a canoe and kayak,but they usually ride inside the bed of the truck.
