Zyvex Technologies claims that its Piranha USV (unmanned surface vessel) is the largest boat of its kind built from nano-enhanced materials. Constructed entirely of Arovex, a nanotube-reinforced carbon fiber, the 54-ft boat weighs only 8,000 lbs. and can carry up to 15,000 lbs. more than 2,500 miles. To stabilize the vessel, Zyvex selected a Seakeeper Gyro Stabilization System. "Stability is especially important on a vessel intended for unmanned operations," said Zyvex director of defense applications Mike Nemeth.
