Sorry for the misleading title; I have a new board that fits nicely on my roof rack upside down with the fin facing the rear of the car, but have been told that it should always go fin forward. To me, this sounds illogical as the fin acts as a wind vane and would tend to keep the board centered if in the rear and might push the board to one side or other if in the front (both scenarios assuming the straps/tie downs loosen up). Also, it looks cooler fin aft.
Why fin front? Thanks
Ps I keep a safety line around the fin, tied to rear strap, to keep the board from possibly sliding aft.
