Effortless sailing

The cloaking craze comes to boating.  The idea is to move the vessel through the water with a minimum of disturbance.

"The goal is make it so the water passing through the porous material leaves the cloak at the same speed as the water surrounding by the vessel," Urzhumov said. "In this way, the water outside the hull would appear to be still relative to the vessel, thereby greatly reducing the amount of energy needed by the vessel to push vast quantities of water out of the way as it progresses."

Perhaps it will be coming to an America's Cup vessel near you.
