Made one for my single scull back in '65 Posted by: g2d on Jan-02-13 12:34 PM (EST)
to move it from Boston to Philly. The car in question was a rented Chevy station wagon, so the spacing on the supporting crossbars was generous.
But on our Accord sedans, Yakima crossbar spacing is under 40 inches, and a longitudinal beam with wide spaced saddles might need addition support so as not to waggle. The cheapest solution might be carefully adjusted end ropes, two at each end for triangulation, tied to the ends of the longitudinal beam, not the boat. The rope should be polyester so it doesn't relax when wet.
Most kayaks and canoes can tolerate close spaced support, as long as the saddles or cradles hit where there is support underneath, like kayak bulkheads.
