Have you tried changing the straps? If you are using ratchet straps,
try rope instead, or some other kind of strap. It is possible that the
noise is not the straps at all.

i have a jeep cherokee, with which i cartop a 14' royalex mad river
adventurer. i use the oe bars, with two nylon ratchet straps across the
body of the boat. the boat itself is supported by foam attachments against
the bars.

i have tried "twirling" the straps, using various tensions on the tie
downs--and nothing works. above 40 mph, this ceaseless, loud droning noise
permeates the car's interior.

surely there is some simple solution. after all, when i left the dealership
with the boat on top, i drove about 75mph for an hour to my destination
without a sound--and the damn straps were absolutely flat.

help! or do i just pop for those thule thingies...?
