Cork surfboards: they float

When Archimedes designed the first buoyancy principle, he was certainly thinking of how to get a surfboard in the water.


"Any object, wholly or partly immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object", stated the Greek mathematician. Today, computers make his job quite well.

From this moment on, all surfboard shapers started to test the best materials to acquire top performance, light weight, design and resistance to impact. Nowadays, everyone knows how to shape a standard surfboard. When building the perfect formula for a champion, the choice of materials is decisive.

If you are simply interested in having fun, why don't you try to shape a cork surfboard? Yes, they are very rare, they float and they are not very heavy. Cork is not everywhere as it only can be extracted in the Southwestern countries of Europe and in the North of Africa. Portugal produces 50% of the world's cork and also has great surfing conditions.

You can also try the wooden surfboards. It is not as easy to shape as cork and there are many related materials to explore, such as balsa. Most of surfboards are made of polyurethane despite the environmental problems but the international production houses are moving to alternatives such as epoxy.

If you are crazy enough, why don't you try a polystyrene (light and fragile) surfboard? Prove yourself you can do it by testing the prototype in a head high wave. Still not happy?

Try the polyvinyl chloride (PVC) surfboard or plexiglas, a transparent thermoplastic that will make sure you can check whether there's a reef in the lineup or if it's only sand.
