What does your SUP carrying vehicle look like...?

98 Ford Ranger, 103,000 miles and rust thru where that salt water from the my Board drips onto the cab

easiest way is by using the Additional options link at the bottom left below the text message box when you are posting.

Here's another thread that discusses it as well but includes posting pics to the gallery here and then cutting and pasting.

Thanks stone....  that made it easy

[TiltPilot]

not taken it too many places yet, but here it is.

Does anyone else worry that it's going to go flying off the roof?  I remember having that feeling when years ago when i first took my surfboard somewhere on the car.  thought for sure it would fly off or snap from the wind  .  Silly me.  I guess i'll get used to it.

Sometimes they do, especially if you forget to put the straps on. Don't ask why I know that.

[surfcal]

We put our fins forward, (see above photo) just in case they slide back maybe the fins will catch.  It also seems to be more areodynamic and helps hold  the board down. (But I'm not a scientiest)

[Tunico Lage]

I HAVE to put the fins forward and pointing down...or it will not pass on my building's garage door!

[linter]

i grew up w/ fins forward and up and my buddies and i would always snicker at those who did it differently.  we figured we were the ones doing it right and they had to be kooks and posers.  ah, youth!

[stoneaxe]

I do it fins to the rear. Not worried about it slipping...we don't use rope anymore..or at least I don't...locking straps and I always double check them. Price of gas...fins to rear is more aerodynamic, especially since the board rocker brings the nose down close to the top of the cab. You'll have to snicker at me linter...

Linter, I had a friend tell me I was a kook because I carried my surf board with the top side towards me. He noted that I at least was cool enough to carry the board with the fin forward. Good thing he didn't see me walk on the beach while wearing my leg rope.

Here's mu Subarghinni not looking very aerodynamic

[PonoBill]

I'm thinking this might be a good basis for a surfmobile. It's a failed TR3 restoration project I bought a few years ago and haven't done much with. I can build a TR3 with my eyes closed, so I should get my ass in gear and do it with a Rollbar/rack. That would be kind of cool I suspect. Be a fun car to take to Maui.
Hmmm. Mobile me images don't seem to work in the forum.

Stoneaxe - not to get too off topic but I remember reading an article in a windsurf magazine on the age old debate of fins forward or back. They did a wind tunnel test and their conclusion was that the aerodynamic difference is negligible with a very very slight nod towards fins up and forward...contrary to intuition. At any rate the difference was tiny. Sorry I don't remember the reference, it was a co-worker's magazine from roughly 6 or 7 months ago.

[PonoBill]

Wow, hard to believe that they'd spend the money for a full scale windtunnel. Somebody must have given them some freebie time. Wind tunnels capable of fitting a full size car rent for several thousand bucks an hour. It takes time to set and test the instrumentation and test the setup. At least three hours for a multiple configuration test like that--figure six to ten K. A 1/4 scale model would be cheaper--you can rent some college low speed tunnels for $300 an hour but that's for walk-in, not drive in sizes. then you have to build accurate models and interpolate the data.

If I was going to do something like that I'd use the car as the wind tunnel. Instrument the rack: springs and strain gauges for lift and drag. Drive down the road and record drag and lift vs. mph. The big advantage of a wind tunnel would be that if it's not a rolling road type tunnel, the baseplate measures drag and lift.

this is all top of mind because I've been thinking of ways to test raceboard hulls without a test tank and building models. Dragging them behind a jetboat with a boom to offset them from the turbulence is what I'm thinking of. this square tail vs. pintail thing has me scratching my head. i'd like to get some real data.

Bill, if you ever read any of the tests in any of the windsurfing magazines (excluding Clay's) you'd know that they never really tested anything, just made it up as they went along.

On another  note, when I was working with windsurfing designers, we'd make a test board with different rails and tail rocker on the top & bottom. We'd then drag the board behind a boat, at different speeds, attached to a fishing scale, with a sandbag on top. We'd then do the same run with the board flipped over on the other side. We assumed the side with the lightest pull would be the fasted.

I wonder what the mpg difference is if your board is fin first in an unzipped bag or open sock looking like a monkfish ready to eat a shrimp like all the numb-nuts I see on the I-5.

My ride is an Element - same as House and Nui Moana man.  I read a Honda design guy in the US brought some of the Japanese engineers down to a well known surf spot where there's a lot of funky rigs and that gave him the acceptance to build the car.  I wish they had a hybrid version but I hear a light diesel version may be coming out soon.   

Other rig is the 2002 Eurovan Westy which is for sale if anyone is looking.  I'll post it up under classifieds.
