I swear by these, they're made for windsurfing boarts. [video=youtube;iJ_c0Dy9U5c]https://www.youtube.com/watch?v=iJ_c0Dy9U5c&sns=em[/video] They sell them on Amazon or you can buy direct from NSI: http://www.northshoreinc.com/store/pc/viewPrd.asp?idproduct=71 I wouldn't be caught dead driving around SoCal with my boards on backwards; but last May on my way up to Butte Co. and then down the coast, I did a fuel efficiency experiment. Unloaded, without racks my cars gets about 40 going 70 on the flats, rhino racks pull it down to 38. On the way up to Chico, fully loaded with a weeks worth of camping gear and luggage, a Thule cargo box, and two boards; I went fins first (although there were no fins in them until we got to Big Sur), set the cruise at 70, and got 32mpg. And the board bag created a big air dam and got covered in bugs. Which sucked cause when we parked and left the car somewhere for exploring/food/piss breaks. I was putting them on the front passenger's seat and locking the car. Heading South to Big Sur, still on the 15, I put the boards backwards. Nose to the bow, fins aft (still no fins in boxes though) and I got about 4 more mpg on the highway with the cruise set at 70. No air dam and the board bag didn't get covered in bugs this time.
^^^Yup... Boards are designed to flow through fluids (yea, air is a fluid) nose first. But think of it this way... lift created by the wide nose and entry rocker forces the nose down when the board is upside down, putting a lot of force on the rack and making the board hinge on the fulcrum. That's a lot of stress on the bottom (tension) and pressure on the deck (compression). I actually buckled a longboard that way driving from MoCo to Cape May. Put it up there tail first and the reduced surface area of the tail, along with the relatively lower tail rocker (compared to the nose) creates much less lift... which is downward force on the rack. One last note... socks are better than coffin bags for car topper travel. Less air resistance, and it still keeps the UV off.
I have ladder racks for my truck, as I used to use it for work. If it's a short bort and only two of them, I just stick them in the bed. More than two short borts or any long bort, they go on top of the rack. I tie them to the racks. Sometimes I put the short borts on the racks too, if it's easier. I can go 80 if they're tied down or in the bed. Probably could go faster than that, if I really wanted to.
Everything goes in the bed of the truck. Surfborts, boogy borts, soccer balls, whiffle ball and bat, beach chairs, power saws, nails, screws, generator, drill, nail guns, level, squares, empty beer bottles, empty tins of Grizzly Wintergreen, tie down straps, loose roofing shingles, the children, the wife. The dog gets to sit up with me in the cab.
I'd really consider putting the boards inside the vehicle and making the wife and kids ride on the roof to be on the safe side. It is a surf trip after all right?
Family trip this time, surf trips in the winter. Plus the forecast isn't very promising for when I'm there.
Yup. And if using a bort bag smooth it out underneath or it's flap city. I just have pads on the racks on the 4-runner, then put tied downs closest to the nose and tail, and bungees more on the inside. I figure it helps to spread out the load\stress on the borts. Regularly do 80 down I-40 and never had any issues. Had to flag a chick down one time who's front straps had come loose and her bort was flying up like two feet off the car. Offered to help her with her straps and rack. She didn't get it. The wife did though, and thought it was hilarious. I married the right woman.
I usually take 5 borts with me when I drive from Jersey to florida every June/July. Like I said, I'll tie them to the ladder racks and even lay some down in the back. We go to venice, but usually go to Cocoa Beach for at least one day of surf. Sometimes Ormond Beach too.
I bought a bus so I just put all my stuff in there. And all my friends stuff. And I can change in it. With 5 other people.
