That brings me onto the guy down my way... He makes Green Surfboards... wait for it... here's his business model;
1) Hand Made
2) Generally copies a mass production board like a 7S Super Fish.
3) Hollow Carbon Fibre Epoxy
4) Orange Resin fins - with a hint of "green" epoxy resin
5) Leashes imported from America which have hemp attachment materials, but new urethane chord.
6) I think he provides a cover, made from hemp!
7) comes with wax, with a green angle...
Out of 10, my grades;
Green - 2.5
Design - 2.5
Concept - 2.5
It's not cumulative... Average is 2.5 out of 10 !!

And they aren't even very light!!

Do I sound jealous, no way!! It's a crap product.
My business model would be;
Green Machines - brand name
Green Resin Tints
Advertise that materials are from the greenest sources available at this time...
If I brought in people like Gerry Lopez, I could be as big as Patagonia after a while!
But big corporates can't be green, with all that transport, and mass costs on shop fronts and fitouts, and advertising... Self defeating greenness!
