If we lived in a world like John Lennon's Imagine would it be possible to produce a windsurfer and sails from natural replenishable resources in a non polluting way? Serious question guys.

Sounds like you need to look at the enviro friendly Hot Sails Maui website, some Superfreaks (Dacron) bring it!

To create plastics, I think you need long chain carbon molecules. Crude oil is one source, I think that you might be able to use vegetable oil as another source?

The critical part of your question is, however: "in a non polluting way".

Do you want to make your gear biodegradable?

Renewable meaning "grows on trees" rather than "is refined from naturally decomposed vegetable matter that's been compressed under the ground for a long time"?

Making a decent 'glue' would be the trick - it would be possible to make a wooden board from laminated balsa or cedar that should be pretty light, but how to stick it together and seal it using a renewable glue or finish?

I guess we could boil up some old horses?

Plenty of naturally occuring fibres around - spiderweb for example puts carbon fibre and kevlar to shame, but we might have to give up our sail windows which would make wave sailing interesting!

Someone is bound to be upset by the boiling of the horses, or the 'battery spider farms' that would be required to make it work. Cruelty to insects and all that..

John Lennon's world is practical only when sitting on a beach watching the sunset while surrounded by a lazy haze of pot smoke... And I suspect that you have to wear coloured glasses to get the full effect.

Speaking of vegetable oil, I saw an article a while back about growing algae on sewage ponds, then harvesting them to get the oils out to make bio-fuel. Apparently you need a sh1t load of algae to make it viable though!

If ony we could take all the carbon everyones producing and turn it into masts, booms, boards etc...would make gear cheaper and solve environmental issues...

(in case anyone thinks I'm serious...)

If we did....not one would work, we'd all be too bent to think (or care) of how to!!!

Great to hear that you are back from the snow. I love the music of John Lennon, to me he and Yoko are one of the greatest love stories of all time. If only all women would stand by their man. He loved his woman and his son and they loved him how romantic.
Remember the people that love you, for in the end the love you take is equal to the love you make.
"To live in a world as one with no religion no wars just love you may say that i am a dreamer"
I like his dream.
Regarding your original question, i love the latest gear, with all that carbon and polyester it has sure developed into light weight high performance gear.
But I would trade it all to live in Lennons dream!

If only John Lennon Hadn't been so Green and used a Kevlar shirt instead of a cotton one he would still be here today.

I reckon you could make a good natural glue from barnicles. Those little pricks really adhere well !!!

Really good question Susie....My understanding is that Mylar has great properties for windsurfing sails but is still very heavy. I can't imagine it would be that outrageous to have an organic product that has the required qualities yet be lighter & better?

I think that a true 'green' kit is possible but would not be up to todays performace.

Boom - Teak(reycled)
mast - Renewable timber
sail - silk
ropes/lines - hemp(no don't smoke it)
board - balsa
base - might be a bit tricky
fin - glass

How you harvest the materials may not be 'green' though!

the surfboard guys i think are leading the industry with bio manufacture.

"quoted"

important developments in the use of new “environmentally friendly” materials for surfboard blanks, cloth, resins, etc. These include “biofoam” (polyurethane foam made locally with less hazardous methylene di-phenyl di-isocyanate [MDI]). Biofoam is produced by replacing the polyol component of the foam with materials converted from natural plant materials, such as soy and sugar. Additional products include bamboo stringer EPS foam, various types of bamboo cloth, and even organic plastic leash plugs made from corn starch. Then there are several people making hollow wood boards with EPS spine and ribs or other internal reinforcing materials, and even a comeback in solid wood boards. Check out the links below for more information.

Boom - willow/bamboo?
mast - i've seen bamboo fishing rods take a caning!!!
sail - ....got nothing!!!
ropes/lines - recycled farmer's 'baling twine' (s@#tloads of the stuff lying around!!!)
board - ....mmmmm, nup, nothing again!!!
base - might be a bit tricky (you're right!)
fin - plantation teak/ebony (bit pricey, though)
