2. Airboat - Wikipedia

   en.wikipedia.org/wiki/Airboat

   The airboat is propelled by a column of air generated by a propeller, with wind speed generated up to 150 miles per hour (241 km/h). Rudders attached to a control stick divert the air to steer. Airboats generally travel at speeds of around 35 miles per hour (30 kn; 55 km/h); modified craft can reach 135 miles per hour (115 kn; 215 km/h).

3. Landing Craft Air Cushion - Wikipedia

   en.wikipedia.org/wiki/Landing_Craft_Air_Cushion

   The Landing Craft Air Cushion (LCAC) is a class of air-cushioned landing craft used by the United States Navy and the Japan Maritime Self-Defense Force (JMSDF). They transport weapons systems, equipment, cargo and personnel from ship to shore and across the beach.

4. Airship - Wikipedia

   en.wikipedia.org/wiki/Airship

   The air-filled red balloon acts as a simple ballonet inside the outer balloon, which is filled with lifting gas. A ballonet is an air bag inside the outer envelope of an airship which, when inflated, reduces the volume available for the lifting gas, making it more dense. Because air is also denser than the lifting gas, inflating the ballonet ...

5. Winch - Wikipedia

   en.wikipedia.org/wiki/Winch

   An air winch, sometimes known as an air hoist or air tugger, is an air-powered version of a winch. It is commonly used for the lifting and the suspension of materials. In the oil and gas, construction , and maritime industries, air winches are frequently preferred to electric, diesel, and hydraulic winches because of their durability ...

6. Hybrid airship - Wikipedia

   en.wikipedia.org/wiki/Hybrid_airship

   A hybrid airship is a powered aircraft that obtains some of its lift as a lighter-than-air (LTA) airship and some from aerodynamic lift as a heavier-than-air aerodyne. A dynastat is a hybrid airship with fixed wings and/or a lifting body and is typically intended for long-endurance flights.

7. Hydrofoil - Wikipedia

   en.wikipedia.org/wiki/Hydrofoil

   When used as a lifting element on a hydrofoil boat, this upward force lifts the body of the vessel, decreasing drag and increasing speed. The lifting force eventually balances with the weight of the craft, reaching a point where the hydrofoil no longer lifts out of the water but remains in equilibrium.
