Why not use di-lithium crystals as a core ?
I am sure the speed sailers would be happy, until they got to warp 10 and Scotty couldn't hold it together.
In fact why not put a Klingon cloaking device on sails and make them invisible to kiters ?
(bollocks - page 6 and it is my fault)
If we only live in Florida and ask the same question on their SB I am sure some NASA windsurfing enthusiasts could perform following simulation in their lunch time break on their supercomputers.
If we take two surfaces 1 cm apart with almost unlimited tensional strenght ( almost or those of carbon nano tube 63,000-130,000 MPa 
) connect this two surfaces by bridges at 90 and 45 degree and pressurise gas between to 100 ; 1000 : 10,000 etc - ( i know it became liquid 
)
what will be max. load on such structure and how if compare to the same made of reinforced concrete or steel.....
Then simulation could take into account required wall thickness required to withstand internal pressure of gases.

As others have pointed out, Macro, if you use a handwavium skin over unobtainium core you COULD get a better board at a cost of just 2.5 smarkakles per drowzium.
In real life, in 2012, that is meainingless gibberish. It takes no brains whatsoever to point out that IF we had new materials developed to a practical and economic stage, then we could use them to make boards. That is so completely self-evident that no one who is not up caught up in their own smugness would bother to say it.
In real life, there are problems. Here's one - what happens in 10 years time when a board pressurized to X KpA develops a minute crack and then explodes, sending shrapnel into the poor sods standing around on the beach?
I have a carbon/kevlar/light foam board from 1982 which is extremely stiff and very tough. It was, and would be, also vastly more expensive than you are talking about.
Board designers are often familiar with what happens in sailboat design, and sailboat designers are quite happy to spend several million bucks per boat on high tech construction. When the space shuttle was launched by NASA, the carbon load bay doors were the 15th-25th (IIRC) largest high-tech pre-preg carbon structures in the world. Number 1-14 were racing yachts. These guys don't just use pro and F1 engineers and aeronautical record holding professors to design boats, they also throw buckets of cash and brains at the problem.
These people are not morons and they have a lot of cash and they use F1 and aerospace technology, but this stuff requires more vastly more cash than you are talking about.
My other sport is cycle racing and they have found nothing higher in technology than sailing boats. IIRC top line bike builders like Cervelo are now building top line bikes in technology that MacConaghy Boats was using in 2001.
You, of course, simply worship yourself and assume that you are smarter than all of the boatbuilders, boardbuilders and cycle builders, but that is your own problem.
BTW the man who basically invented the sport and worked with Starboard for years WAS a former NACA geek. by the way. Do you think that he may have had some idea about tech?
I wreckon these super sonic new boards will be filled with a lot of 'hot air'.....!!!
and before any starts...yep there has been a board that was 'air filled' from Europe few years ago...was pretty good 'when' it worked...
Macroscie or whatever the f=ck you call yourself you are a f*cking idiot. In all my years of wind/water sports I have never come across such a complete d+ck head. Get a grip (if you have one to grab) and go back to your nerd camp and design your one design $5 board you f8cking tool.
Spiderwebs are the strongest fibres for their weight.... or sectional density to length ratio or something. Whatever.
I am gettign aheap of spiders and puttign them nside a hollowed out board.
I just pumped LSD fumes threw the board, and played techno music (hard tyrance seems to be best) and they are going like crazy little fibre weavers lol and the board is now fille dwith spider webs. Sik!
I took the hull off and I have a lattice like that nasa really lite nanotube ones on top of the daffoldil, and it is the shape of the board, exactly. now I have elctrostatically charegd it with a car battery so the epoxy resin I have sprayed itnot the air will stick to it.
So far it has cost me 1 x tachno CD, 2 x trips and a bottle of West 105 resin which is $110 all up.
It is really stiff.
Then I will laminate it with G11 (G10 is sooo old skool)
I cna do boards for $300 easy for SB memebers.
Since nobody is reading or trying to understand anything I could keep writing for myself end future generations.
Design the concept board construction your grand kids will be using.
You asked Mark what construction, then after while I come up with technological process.
Steps to create 3D board.
1. First we prepare cuboid slightly bigger of boar made of foam weaved with carbon fibres going vertically (90 degree) and 45 degree's in all directions
Foam is used to stabilize delicate carbon matrix
2. Robotic laser will cut from this cuboid precisely desired board shape
3.Next process remove marginal foam to release few millimetres of fibre at surface
4.Applying external skin made of composite carbon fibre and desired bond (epoxy or polycarbonate etc)
5.External skin of board consist then of the reinforcing carbon canvas and anchored fibres penetrating foam foam across.
Now depending on desired mechanical properties internal foam could be removed (dissolved for example) and replaced with other material or gas or liquid.
Could be also left if have sufficient mechanical properties ( for compression)
Such rough prototype could be made even today by weaving traditional board filler with carbon or kevlar thread to be bonded later with external layer -board skin.
OK I think that will be enough... now I could move to Stephen Hawkins to improve on his quantum theory....
Congrats Macro...6 pages of complete drivel (from all sides) & still going strong.
SB thread of the year award goes to...
Ahh, the irony is great... people asking the thread to be stopped 'by posting to the same thread'
Don't you guys know that the best way to kill a thread is to stop reading it, and most importantly stop replying to it? [}:)] Why would a moderator stop something when you don't have enough self-control to stop yourself from reading it?
I for one have been enjoying this thread
Cant decide if I want an unobtanium core or a spider web one and I,m still trying to find out the exchange rate between AUD and drowziums
Now just waiting to be told that we are all part of an elaborate social experiment.
Has anyone thought of Papier-mâché/cardboard construction? This is the obvious solution, 100% carbon boards, cheap... Plus you would never get any water inside cause there is a balloon in there!!!
I'm surprised no one has mentioned using the Higgs Boson in the construction. Better still some dark matter would be excellent.
This thread is like a train wreck, car crash and mid air collision all wrapped into one - you just can't help but look
EDIT - Damn, still on page 6
The answer to all your questions can be found in coconut fibre, banana skins and quinoa!
