An airboat , also known as fanboat , is a jon boat propelled by aircraft propellers and powered by aircraft or automotive engines. They are usually used for fishing, bowling, hunting, and ecotourism.
Airboat is a very popular means of transport in marshy and/or shallow areas where inner standards or outboard engines with submerged propellers will be impractical, for example, in the Florida Everglades, part of Indian River Lagoon, Kissimmee and St.. Johns Rivers, and Louisiana Bayous.

The distinctive underground aircraft design, together with the fact that there is no operating part below the water surface, allows easy navigation through shallow swamps and swamps; in canals, rivers, and lakes; so is the frozen lake. This design also makes it ideal for flood and ice rescue operations.
The airboat is pushed forward by the propeller, which produces the rear air column behind it. Washing the resulting prop is an average of 150 miles per hour (241 km/h). Navigation is done by diverting left or right air columns while passing through the steering wheel, controlled by the pilot through the "stick" located on the left side of the operator. Drive and control as a whole are functions of water flow, wind, water depth, and drive propellers.
Stopping and reversing direction depends on the skill of the operator/pilot/driver is good because the airboat does not have brakes. They are unable to travel in reverse, unless equipped with an invertible propeller. Some designs use inverted shell turning devices intended to brake or reserve very short distances but these systems are not commonly used.
Operator/pilot/driver, and passenger in many ways, sitting on a high chair allowing visibility of swamp vegetation. High visibility allows the operator and passengers to see floating objects, stumps and animals on the ship's lane.

History
The world's first underground air boat was discovered near Brigham City, Utah in 1943 by Cecil Williams, Leo Young, and G. Hortin Jensen. The purpose of the ship is to help preserve and protect bird populations and animal life in the world's largest migratory bird sanctuary. The Bear River Migratory Bird Refuge near Brigham City, Utah is located as a wetland oasis in the middle of the Great Basin Desert. This is an important stop for migratory birds in North and South America. The need for practical ways to help navigate challenging environments in wetlands, shallow water, and thick mud helps inspire, Cecil Williams, Leo Young, and G. Hortin Jensen to make average air-propeller boats. The subsequent design and upgrading and practical use of the air thrusters seems to have been a collaborative effort. Williams, Young, and Jensen are employees of the Bear River Migratory Bird Refuge, a division of the US Fish and Wildlife Service. LeeRue Allen, who worked at Refuge since 1936 seems to have also been involved and helped to document the history of the event.
The ship is in a museum display at Migratory Refuge Bird Park, near Brigham City, Utah and has also been exhibited at the National Conservatory Training Center in North Carolina. It has also been exhibited at the Bayou Black Lake Wildlife Sanctuary in Louisiana.
In 1943, at Bear River Migratory Bird Refuge in northern Utah, Cecil S. Williams and G. Hortin Jensen sought a solution to the problem of conducting avian botulism studies in shallow, swampy hinterlands. Using a 40-horsepower Continental engine powered on a 12-foot, flat-bottomed aluminum vessel, they come up with one of the world's first air boat designs. The original airboat had no seat and the pilot knelt on the boat. They call it Alligator I. The current air boat is a popular mode of transportation for researchers and tourists in wetlands around the world.
A 1987 story in Unlimited Duck magazine mentions Young and Jensen and the date of the first boatbuilding in 1950. The safeguard records, however, showed the first boat to be used in 1943, with several aerial photographs flowing. Boats dated 1947. Prior to the introduction of airboats, refugee biologists had to travel through shallow water and deep or sticky mud or push uninterrupted underground boats with long poles. Staff have experimented with boats called "Mud Queen," which have small paddle wheels on both sides that drive the boat. They built their first airboat dubbed "Alligator I" from an underground boat driven by an aircraft engine purchased for $ 99.50. Young reports that he calls the first airboat an "air booster". As soon as news comes out about the boats, Leo Young builds and sells boats all over the world.
Many of the early craft built on the shelter were shipped to Florida. Early records indicate a cost of about $ 1,600 to build boats, including engines.
While a number of claims have been raised about the discovery and use of the first air boat, the most documented, supported, verified claim claims seem to be the world's first underground air boat found near Brigham City, Utah in 1943 by Cecil Williams. , Leo Young, and G. Hortin Jensen. The practical value, use, and awareness of this first flat-bottomed flatter air boat quickly found widespread use worldwide.
Allegedly the motor aircraft was suspected to have been tested using a special boat. Allegedly one of the first of the "airboat" type, called Ugly Duckling, was built in 1905 in Nova Scotia, Canada by a team led by Dr. Alexander Graham Bell. It is used to test various engines and configuration of fishing rods. It has not been clearly documented or supported or no clear date has been verified and assigned.
Glenn Curtiss is credited with building a kind of airboat in 1920 to help facilitate his hunting hunting and bowling in the Florida hamlet. The millionaire, who later develops the cities of Hialeah and Miami, combines his aviation and design talents to facilitate his hobby, and the end result is 'Scooter', 6-passengers, closed cockpit, propellor - Motor boat driven by an aircraft engine suspected to slip through the wetlands at a speed of 50 mph.
Over the years various designs have been attempted and through trial-and-error, the standard designs used nowadays are: flat, open bottom boats with rear mounted engines, drivers sitting in elevated positions, and cages to protect propellers, the blades of the objects flying into them.
Here are some airboat pictures.
Producing
Airboat manufacturers tend to be small, family run businesses that assemble built-to-order vessels. Airboat is also produced in Russia, Australia, Italy and Finland.
Modern and commercially manufactured hull airboats are made of aluminum or fiberglass. Material selection is determined by the type of field in which the vessel will be operated. The standard hunting/trailing boat has a length of 10 feet (3.0 m) with a capacity of two to three passengers. Tour boat can be much larger, accommodating 18 passengers or more.
The engines are air-cooled, 4- or 6-cylinder or water-cooled, large-displacement, V8 automotive engines ranging from 500 to more than 600 horsepower (450 kW). Automotive engines tend to be cheaper because of available parts easily and cheaper high octane gas. Because the opposing, 4- or 6-cylinder (O4 or O6) power plants contain fewer moving components than standard automotive engines, it's easier to fix and weigh less. Most reciprocity generators can be lowered to burn 87-octane automotive gas than more expensive aviation gas.
Most of the sound produced by the airboat comes from the propeller although the machine itself also accounts for the noise. The modern airboat design is significantly quieter thanks to mufflers and multi-blade carbon fiber propellers.
Security
Knowledge of operational safety is essential when operating an airboat.
Engines and propellers are enclosed in protective metal cages that prevent objects, such as tree limbs, branches, clothing, beverage containers, passengers, or wildlife, from contact with rotating blades, which can cause severe damage to the ship and injury traumatic to operators and passengers. If the tree branch enters the propeller, the material spray can be damaging, causing damage to the ship and injury to the ship's inhabitants.
In 1998-99 S. Fish & amp; The Wildlife Service's National Wildlife Conservation Training Center, located in Shepherdstown, West Virginia, and working with the US Technician Corps in Jacksonville, Florida, produced a 70-minute training video entitled Airboat Safety - Design-Operations-Maintenance . This video covers the initial history of airboats and interviews with two airboat manufacturers in Florida. It was considered the only aircraft video of its kind when it was made and may still be the only one with a variety of airboat material ever produced in the US. Since it is produced by a Federal Agent, it is in the public domain, and is not copyrighted. 500 copies of the video are produced.
On March 30, 2018, Governor Rick Scott of Florida signed "Ellie's Law," which required operators to complete CPR instructions and courses on air boats run by the state wildlife commission. The law is named after Elizabeth "Ellie" Goldenberg, who died from an airboat accident in Miami-Dade County the day after her graduation from college. Starting July 1, 2019, airboat operators must be able to show evidence that they have completed the training. Violation is a minor offense punishable by a $ 500 fine.
Rescue
In recent years, airboat has proved indispensable for flooding, shallow water, and ice-saving operations. As a result, their popularity is increasing for the use of public security.
During floods in New Orleans after Hurricane Katrina, August 29, 2005, aircraft from across the United States saved thousands of flood victims. Thirty airboats evacuated more than 3,000 patients and medical staff from four downtown New Orleans hospitals in less than 36 hours.
Many articles have been published in fire safety trade journals explaining the advantages, abilities, and benefits of using airboats for water-saving operations, and provide an in-depth description of actual water-saving incidents, including the New Orleans flood.
Airboat is also used by US Military, U.S. Coast Guard, and US Border Patrol. During the Vietnam War, Aircat Hurricane aircraft were used by US Special Forces to patrol in areas where larger ships could not go. They are also used in Iraq and Texas for border patrols. The Nov/Dec 2007 issue of Airboating Magazine contains an article on airboats used in Vietnam and in Iraq and has many articles on airboats used by the US Coast Guard and other state and county EMS units to save ice fishermen and save them in floods and after the wind typhoon.
