How are hovercrafts steered?
A downward-pointing fan can only blow air underneath, so hovercraft typically have one or more propeller fans on top of the hull, pointing backward to propel them forward. Usually, there's a rudder positioned just behind each fan to swivel the air it produces and steer the hovercraft in the appropriate direction.

Over 15 years, LCAC assembled volunteers to install water, toilets, electricity, a kitchen, and heaters, as well as to tend to needed repairs. These LCAC volunteers created a venue that for 50 years hosted arts festivals, Sommerfest celebrations, fund-raisers, dog shows, and even weddings. With extensive renovations required by the ADA, the Barn’s fate is uncertain. LCAC hopes that LARPD and the City of Livermore will take into consideration its contributions in determining its ultimate destiny.

What is a UHAC?
Since 2008, the Office of Naval Research (ONR) has been working with ship-design company Navatek to develop an entirely new kind of beach stormer called the Ultra Heavy-Lift Amphibious Connector (UHAC). The vehicle is unique for two reasons. First, it’s massive. UHAC should be able to haul three U.S. Abrams main battle tanks at a time, compared to just one on an LCAC. Second, it’s light. Air-filled foam treads give the fully loaded vehicle a ground pressure of just a few pounds per square inch—lighter than an adult human’s footstep. “In places where a person would sink into the mud, UHAC would walk right over,” says Frank Leban, deputy UHAC program manager at ONR.
How does a hovercraft work?
The basic mechanism of a hovercraft is very simple: there's an engine ( diesel or gasoline) that powers both a large central fan, pointing downward, and one or more other fans pointing backward. The central fan creates the lift that holds the craft above the wa ves; the other fans propel the craft backward , forward, or to the side.
Why are hovercraft not used everywhere?
But if hovercraft are so wonderful, why aren't they used everywhere? They're expensive initially and, though cheaper than helicopters, considerably more costly to maintain than ships and boats of similar cargo capacity (because they're essentially aircraft, not boats, and mechanically more complex). Although hovercraft successfully carried tens of millions of people between Britain and France for just over 30 years, they eventually stopped operating following the opening of the Channel Tunnel and the arrival of low-cost ferry ships and fast, wave-piercing catamarans. Hovercraft are also fairly tricky to pilot: more like helicopters, in this respect, than simple-to-operate boats. They're very noisy too, which can be a problem both for passengers and people living near the ports where they operate, and is certainly a drawback for "covert" military operations.
