Hovercraft - Ultimate Amphibious Machine

Every Wednesday we present a new video, so join us to see the truth laid
This machine breaks all the rules, it can penetrate some of the toughest
terrains on earth, over land, over water, from the polar ice, to the rapids
of the Amazon. This is the ultimate frictionless floating machine, the
A hovercraft, also known as an air-cushion vehicle or ACV, is a craft
capable of travelling over land, water, mud or ice and other surfaces.
Hovercraft are hybrid vessels operated by a pilot as an aircraft rather
than a captain as a marine vessel.
Hovercraft use blowers to produce a large volume of air below the hull that
is slightly above atmospheric pressure. The pressure difference between
the higher pressure air below the hull and lower pressure ambient air above
it produces lift, which causes the hull to float above the running surface.
For stability reasons, the air is typically blown through slots or holes
around the outside of a disk or oval shaped platform, giving most
hovercraft a characteristic rounded-rectangle shape. Typically this
cushion is contained within a flexible "skirt", which allows the vehicle to
travel over small obstructions without damage.
The first practical design for hovercraft derived from a British invention
in the 1950s to 1960s. They are now used throughout the world as
specialised transports in disaster relief, coastguard, military and survey
applications as well as for sport or passenger service. Very large
versions have been used to transport hundreds of people and vehicles across
the English Channel whilst others have military applications used to
transport tanks, soldiers and large equipment in hostile environments and
US Navy LCAC (Hovercraft) Landing at Ocean Beach, San Francisco
tl;dr: skip to 4:45 for the landing.
This is a long cut of the video I took of the San Francisco Fleet Week
Medical Exchange Exercises that were performed on Ocean Beach. The main
of attraction of which was the Navy Landing Craft Air Cushion (LCAC)
landing on the beach (at 4:10 on the video) and the subsequent 180 degree
turn and departing (10:00), however there were many other vessels,
watercraft, vehicles, helicopters and other activity. Even a visit by the
Mayor at (7:15).
Here's how the event was described:
Since 2010 San Francisco Fleet Week has been the venue for Bay Area First
Responders and the U.S. Military to meet, train together and discuss the
latest lessons learned from recent Humanitarian Assistance and Disaster
Response operations and to develop processes and relationships between
Federal, State and Local agencies.
As part of 2012 Fleet Week activities, the San Francisco Fleet Week
Association and the San Francisco Department of Emergency Management along
with the U.S. Navy and Marine Corps team in action as a Navy Landing Craft
Air Cushion (LCAC) operating from the USS Makin Island (LHD 8) and Marines
from the 1st Marine Expeditionary Brigade deliver emergency supplies to
Ocean Beach on October 3. This event is part of a multi-agency medical
The Navy LCAC is an amphibious military vehicle that provides a high speed,
over-the-horizon transport of cargo, vehicles, and personnel from Navy
ships at sea to beaches and other landing sites. The Navy and Marine Corps
used the LCAC to deliver equipment and supplies to Louisiana following
Hurricane Katrina, to deliver fire suppression apparatus to Catalina
Island, and to support disaster relief missions around the world.
Following a major disaster in San Francisco that makes roads and bridges
impassible, Navy LCACs and other amphibious vehicles and aircraft could
deliver critical personnel, supplies, and equipment from Navy ships at sea.
This exercise will demonstrate the humanitarian assistance and disaster
relief capabilities of the Navy and Marine Corps team to deploy the LCAC to
deliver emergency supplies, in this case to a Marine Corps Shock Trauma
Platoon (STP). The STP, which will also be demonstrated at Ocean Beach, has
the unique capability to establish a mobile surgery center within hours of
a major disaster to provide medical attention to those in need.
