The design and technology of this hydroifoil boat reduces drag, increasing speed and efficiency. This ship gives you the feeling of flying, and when landing it goes into the water like a regular ship.The Boeing JETFOIL (Boeing Model 929) was designed for passenger comfort at high speeds.

It gave passengers a smooth and fast ride, and its three narrow struts created a fraction of the wake that a ship of its size would normally make.It was also as quiet as a conventional auto ferry. With a stopping distance of 152 meters and a turning radius of just 196 meters, it was easy to maneuver the 27-meter-long ship through congested waterways.


The JETFOILs were powered by a pair of Allison gas-turbine engines that each drove a Rocketdyne waterjet pump, which propelled the 115-ton vessel at speeds in excess of 45 knots -51.8 mph.
