ok so you may not care about looks, great. But if you want to transport safely and with the least amount of drag and upward pressure on the board go nose down, fins up (remember to check clearence of fins to garage door)
Instersting. Actually if you want least amount of drag and upward pressure on the board it is fins up and tail to the front of the car.
Think about the profile of a board with the nose forward and fins up, it shares some of the same characteristics as a wing. When driving at speed this will create lift and upward pressure on your straps. That lift also creates some drag.
Nose to the back and fins up doesn't induce any lift and by the time air flow hits the downward facing nose at the back of the car two things are happening, the slight deflection is pushing on the rear strap levering the board to the rack, but mostly the air is so broken up by the board, the racks, the roof line of the car and deflection from the windscreen etc it is actually doing nothing. So you have neither lift nor great downward force.
Do a search on the internet, you will find more people agree with this than disagree.
