I have been looking into doing this myself. I was thinking of taking the lines off my friends SUP, or buying the frames from Fiberglass supply
http://www.fiberglasssupply.com/html/stand_up_paddleboard_-_hollow_.html

I will either skin it, with one to three layers of veneer set in epoxy: stitch and glue thin marine plywood: or strip plank it.

Grain Surfboards makes some sweet kits as does Chesapeake Light Craft.

You could potentially build a hollow surfboard/windsurfer that is lighter and stiffer than the current method.
Wood already has torsion and compression stability before you add epoxy resin. Plus itís cellulous structure mean you can use less resin than with carbon fiber. And itís the resin that weighs so much: not the carbon.
I think that if you orient the stringers, ribs, and skin properly; you could produce a lighter, stiffer, and more durable board than is the norm.

No, you can not!
It's been tried by better wood builders than you, from Woodwinds thru those hollow AHD guys, from Efferding to Doyle, to any hundreds of private backyard finish and master carpenters.
You can make it light, but it won't last nearly as long as a Thai, Spanish, Algerian, or Czech made production board.
And local Cz guy makes the lightest, strongest windsurfing boards of ANYONE, for the last 15 years, using simple styro/glass technology.
You think you are pioneering new tech. NOPE, been done, been tried, always failed, EVERY time.
Now if you were an accomplished windsurfer, then you MIGHT have a nearly zero chance. Now, you have no chance whatsoever.
Go for it, reach for your dreams, but it's all been proven done and packed away.

BS, Damon. I own a hollow AHD 98NT FW board from 2003. It's sailed hundreds of days since first hitting the water and has the same rocker as when it came out of the box. That board is, by far, the strongest and stiffest board for the weight I've ever owned. The only damage is a slight pressure dent in the rail from when the sail rolled over in heavy air. Otherwise, it's been bulletproof.

LeeD, this is the kind of thinking that almost killed windsurfing in the 90s.

Yea, there have been a lot of poorly executed "innovations" in our sport; luckily, Windsurfing has always been about innovation and re-trying old failed ideas.

MY god, Quads are back; wood decks, skinny masts, Dacron sails, oval aluminum booms, longboards!... The list goes on.

Hell,, why stop with the board. Some guys build their own sails too. If you've got the time and money to waste,, why not??? Shocked Shocked

Sorry I am a bit late on the reply, but it is possible to build wooden sailboards even at weights comparable to cobra boards. There are a number of different construction methods. The time taken to build out of wood is definitely much greater than building out of foam. As Westender says If you've got the time and money to waste why not? Well it is always a very satisfying moment when you get to sail a board that has been created by your own hands, be it wood, foam or whatever material. As for the money for a slalom board it costs around $300 - $400, so it is not the end of the world if it sinks.
The methods that I have used are to build a plywood frame and then a ply deck and bottom with balsa rails. This makes the deck largely too flat. The last one (3rd picture) is made with a ply frame and then skinned with 1/4Ē paulownia (a wood that is a bit lighter than cedar) top and bottom with a domed deck. This also took off several pounds from the finished weight. Building out of wood other than balsa the weight will always be heavier than a foam sandwich board by about 15 Ė 30%. For free sailing this isnít a issue at all.
For light weight, balsa construction is the go. The problem here though is that if water gets in the balsa will rot quicker than other woods. Having said that if the build is good it can last for years. This 4th board is from another forum posted a couple of years ago. At the time it was 10 years old.For its construction method see this link http://www.grainsurf.com/forum/viewtopic.php?f=11&t=375

That 4th board is getting there. What's it weigh, and does it handle the heel impacts from sailing, does the mast track stay watertight, does the finbox?

That last one is not mine. Here is the link to that one but there isn't much info on it except that the weight is about 5 kilos & 10 years old, so i guess it is water tight and has held up to use. It was posted in 2007.

PS the 3rd one weighed 7 1/2 kilo before the straps.

Starboard has it right, the only good wood (on a WSing board) is a thin wood veneer over a strong, light weight foam core.
You can still build your own, get into vacuum bagging the veneer on and you have your "wooden" board.
