A hovercraft is a versatile vehicle that can travel over land, water, and other surfaces by creating a cushion of air beneath it. This is achieved through large fans that push air downwards, allowing the hovercraft to float above the ground or water. Hovercrafts are often used for transportation, rescue missions, and recreational activities. One of the key advantages of hovercrafts is their ability to navigate shallow waters and marshy areas where traditional boats cannot go. They can also operate in various weather conditions, making them useful in emergencies. Hovercrafts are commonly used by organizations like coast guards and search and rescue teams.
