Usually i do not post articles about boats and sailing ,unless they are something really interesting.Tis is probably the most ineteresting rticle i ve read for a while,thus repost

Boats had been built for millennia using biodegradable and sustainable materials. Most of the time it was wood or bark, like the canoes of the North American Indians, or even animal skin. In the last 100 years however wood started to become less available and more expensive for boat building. Meanwhile progress in the industrial manifacturing of metal made it possible to build metal hulls. Big ships needed a solid structure due to their size but also pleasure yachts started to use the same technology, and  steel and aluminum are broadly utilized. Finally reinforced plastic (fiberglass) appeared as a convenient technology to build boats that were cheaper, lighter, and strong, due to the elasticity of this material that makes it so forgiving. Yacht design in recent years started to look into new syntethic fibers, like carbon fiber and Kevlar, to build lighter and stiffer boat, expecially racing sailboats.

Natural fiber…
