The Boeing 929 Jetfoil is a waterjet-driven hydrofoil that can carry passengers. It was introduced in 1974, has two Rolls-Royce Allison 501KF gas turbine engines, and can travel at a 45 knot speed with up to 350 passengers on board.

 

The Jetfoil propels itself forward using its water jet propellers that are driven by gas turbines, and it flies over the water’s surface using the dynamic lift provided by its fully submerged forward and aft foils that are attached to the hull by struts.

 

A jetfoil’s motion is quite comparable to an airplane’s. The Automatic Control System (ACS) controls the movement of the submerged foils’ associated flaps, which are employed for attitude control to keep the hull at a set height above the water’s surface and to guide the ship to port or starboard.

 

In fact, the Jetfoil is an “airplane in the sea” because it gets its dynamic lift from sea water rather than from air. The fact that water is 800 times denser than air allows the jetfoil to fly slower and with smaller wings than an airplane. The Boeing Company in Seattle, USA, made 20 of the 35 Jetfoils that are currently in operation around the world.
