Airboating is a popular attraction in the FloridaAn airboat, also known as a fanboat, planeboat, swamp boat, or bayou boat, is a flat-bottomed propelled by an aircraft-type and powered by either an aircraft or automotive engine. They are commonly used for fishing, bowfishing, hunting, and.Airboats are a very popular means of transportation in marshy and/or shallow areas where a standard inboard or outboard engine with a submerged propeller would be impractical, most notably in the Florida but also in the, the and rivers, and the and, as well as the. Contents.Overview The characteristic flat-bottomed design of the airboat, in conjunction with the fact that there are no operating parts below the, allows for easy navigation through shallow swamps and marshes; in canals, rivers, and lakes; and on ice and frozen lakes. This design also makes it ideal for flood and ice rescue operations.The airboat is pushed forward by the propeller, which produces a rearward column of air behind it. The resulting averages 150 miles per hour (241 km/h). Steering is accomplished by diverting that column of air left or right as it passes across the rudders, which the pilot controls via a 'stick' located on the operator's left side.
Overall steering and control is a function of water current, wind, water depth, and propeller thrust. Airboats are very fast compared to comparably-sized: commercial airboats generally sail at speeds of around 35 miles per hour (30 kn) and modified airboats can go as fast as 135 miles per hour (117 kn).Stopping and reversing direction are dependent upon high operator skill, since airboats do not have brakes. They are incapable of traveling in reverse, unless equipped with a. Some designs use a clam shell reversing device intended for braking or backing up very short distances but these systems are not commonly used. The operator and passengers, are typically seated in elevated seats that allow visibility over swamp vegetation.
High visibility lets the operator and passengers see floating objects, stumps and other submerged obstacles, and animals in the boat's path.In the United States, a typical good-quality airboat costs between $33,000 and $70,000. In a developing country like Iraq, however, an airboat can be purchased for as little as 2.5 million, or $2,147. In spite of their high cost, airboats are very widely used by civilians and tour operators: there are 12,164 airboats, 1,025 of them commercial, in Florida alone as of December 2017.
Airboats are widely used in other states, especially, but they can be found in rivers, marshes, and icy areas around the world, from to.Soviet airboats and aerosleds. Main article:Airboats and airboat-like craft have been used in the and its successor states since the and possibly earlier. Some true airboats—vessels that operated entirely in the water—were used by the Soviet military in. These true airboats include the, a 1,200-kilogram (2,600 lb) WWII armed boat reportedly capable of speeds up to 60 kilometres per hour (37 mph; 32 kn).
However, most Soviet airboats are (referred to as 'aerosanis' in Russian). An aerosled is an aircraft propeller driven amphibious vehicle best described as a hybrid of a sled, airboat,. Thousands of aerosleds were used as cargo and passenger vehicles in, where they excelled because they could cope equally well with the icy Siberian winter and the muddy, marshy conditions of season (similar to the American ), when raw or thawing snow makes travel by road impossible. Aerosleds are still in use today. The is a quintessential example of this type of vehicle; it can reach speeds of up to 120 kilometers per hour (74.6 mph) on snow and 65 km/h (40.4 mph) on water. History The first airboat was invented in 1905 in. The earliest airboats to see any kind of use date to 1915, when airboats by the in the World War I.
However, airboats were not widely used by civilians until the 1930s. First prototypes. Early airboats in in 1918The first airboats to see any real use date to 1915. The used airboats, which they referred to as Lambert 'Hydro-Glisseurs', in the of the. These 'Hydro-Glisseurs' were small, flat-bottomed with wooden hulls propelled by a large aircraft fan that allowed them to reach speeds of up to 55 miles per hour (48 kn). They were primarily used for reconnaissance on the.
The first of these airboats, HG 1 Ariel, was constructed using the engine and propeller of a wrecked biplane and was provided to the forces in Mesopotamia by the. Following Ariel's successful deployment in the campaign upriver to in 1915-1916, Britain ordered seven purpose-built airboats from 's eponymous company De Lambert. Eight of these vessels were in operation in 1917, increasing to nine by the 1918.
A dedicated repair slipway for these boats was built at the Motor Repair Dockyard in, indicating both their importance to the British war effort and the difficulty of maintaining them.: 67-8. A 1917 cover depicting a British Army airboat on the in IraqFollowing the war, Lambert airboats were used as ferries on the shallow waters of the, on the, and elsewhere. Like their military counterparts, these airboats were manufactured in France, though they were assembled in. They had of only seven inches and could cruise at up to 32 miles per hour (28 kn). Lambert airboats were also used widely on the upper and on the marshes of the., the company that built the engines for the WWI military airboats, began producing civilian airboats in the 1920s. It marketed airboats for use as and as light cargo vessels or for French colonial governments. Its airboats sold for 25,000 to 50,000 depending on the model, a price that proved too steep for potential buyers; the company pulled out of the boat business by the end of the 1920s.
Airboat prototype Le Ricocheur in 1924. She was capable of speeds of up to 125 km/h (67.5 )These early European airboats were significantly different from their modern counterparts. Compared to the airboats of today, early European airboats tended to be somewhat larger, had higher, and lacked a protective cage surrounding the propeller. They also had a different steering mechanism: early airboats were steered with a in the water controlled by a with throttle control provided by a, like an.
More modern airboats use an controlled with a for steering.Early American airboats. Cecil Williams operating Alligator I, one of the first airboats, at in 1946is credited with building a type of airboat in 1920 to help facilitate his hobby of bow and arrow hunting in the Florida backwoods. The millionaire, who later went on to develop the cities of and, combined his talents in the fields of aviation and design to facilitate his hobby, and the end result was Scooter, a 6-passenger, closed-cabin, propeller-driven boat powered by an aircraft engine that allowed it to slip through wetlands at 50 miles per hour (43 kn).Airboats began to become popular in the United States in the 1930s, when they were independently invented and used by a number of Floridians, most living in or around the Everglades. Some Floridians who invented their own airboats include frog hunter Johnny Lamb, who built a 75-horsepower airboat in 1933 he called the 'whooshmobile' and Gladesmen Ernest and Willard Yates, who built an airboat in 1935 they steered via attached to a crude wooden rudder. Yates holds the ignomious honor of being the first person to die in an airboating accident, when the engine dislodged and sent the spinning propeller into him.An improved airboat was invented in Utah in 1943 by Cecil Williams, Leo Young, and G.
Hortin Jensen. Their boat, developed and used near, is sometimes erroneously called the first airboat. At the in northern Utah, Cecil S.
Williams and G. Hortin Jensen sought a solution to the problem of conducting avian studies in the shallow, marshy hinterlands.
By installing a 40-horsepower aircraft engine, purchased for $99.50, on a flat-bottomed 12-foot long aluminum boat, they built one of the first modern airboats. Their airboat, pictured here, had no seat, so the skipper was forced to kneel in the boat. They dubbed it the Alligator I as a response to a joking comment from headquarters that they should 'get an from Louisiana, saddle up and ride the critter during their botulism studies.'
Their airboat was the first to use an air rudder (a rudder directing the propeller exhaust rather than the water), a major improvement in modern airboat design.The purpose of Williams, Young, and Jensen's airboat was to help preserve and protect bird populations and animal life at the world's largest migratory game bird refuge. The Bear River Migratory Bird Refuge near is a wetlands oasis amid the and an essential stopping point for birds migrating across North America. The need for a practical way to navigate a challenging environment of wetlands, shallow water, and thick mud helped inspire Williams, Young, and Jensen to create the flat-bottom airboat, which they initially called an 'air thrust boat.'
Designs and subsequent improvements and practical use of the air thrust boats appears to have been a collaborative effort. LeeRue Allen, who worked at the Refuge since 1936 appears to have also been involved and helped to document a history of the events.Many of the early airboats built at the refuge in Utah were shipped to Florida. Early records show it cost roughly $1,600 to build a boat, including the engine.Over the years, the standard design evolved through trial-and-error: an open, flat bottom boat with an engine mounted on the back, the driver sitting in an elevated position, and a cage to protect the propeller from objects flying into them.

The uses an airboat to collect herbicide-resistant from in northern Florida Manufacture and design Airboat manufacturers tend to be small, family run businesses that assemble built-to-order boats. Most airboats are manufactured in the United States, although they are also built in, and elsewhere. Prior to 1950, most airboats were manufactured in France by companies and individuals such as, and.Modern, commercially manufactured airboat hulls are made of aluminum or fiberglass. The choice of material is determined by the type of terrain in which the vessel will be operated; airboats intended for use in icy conditions will have sturdier polymer coated aluminum hulls while airboats intended for use in marshes will have lighter fiberglass hulls, for instance. Standard hunt/trail boats are 10 feet (3.0 m) long with a two- to three-passenger capacity.
Tour boats can be much larger, accommodating 18 passengers or more.Engines are either an air-cooled, 4- or 6-cylinder aircraft or water-cooled, large-displacement, V8 automotive engine, ranging from 50 to over 600. Automotive engines tend to be less expensive due to readily-available replacement parts and less expensive automotive gas. Since an opposed, 4- or 6-cylinder (O4 or O6) aircraft powerplant contains fewer moving parts than a standard automotive engine, it is easier to repair and weighs less.
However, automotive engines can be repaired by more-common car mechanics and do not require specialized repair personnel like aircraft engines do.Most of the sound produced by an airboat comes from the propeller, although the engine itself also contributes some noise. Modern airboat designs are significantly quieter thanks to mufflers and multi-blade carbon-fiber propellers. Safety. Aft view of a safety cage during operationAs with any vehicle, the safety of an airboat is dependent on the training and skill of its operator and the use of safety features like seat belts and /life jackets. Airboats should only be piloted by trained and qualified operators, and knowledge of operational safety is essential when operating an airboat.Over 75 airboat accidents happened in Florida between 2014 and 2017, resulting in seven deaths and 102 severe injuries.
Most (five of seven) deaths were drownings, and 90 percent of accident victims were not wearing, even though only 30 percent knew how to swim. Not wearing a is another major predictor of injury in an accident: 40 percent of injured victims and the only two non-drowning fatalities were flung from their seats in the crashes. The most common injuries suffered in airboat accidents are severe cuts, bruises, and broken limbs.
A resident is transported by airboat after Hurricane KatrinaIn recent years, airboats have proven indispensable for flood, shallow water, and ice rescue operations. As a result, they have grown in popularity for public safety uses.During the flooding of following, August 29, 2005, airboats from across the United States rescued thousands of flood victims.
Thirty airboats crewed by civilian volunteers evacuated over 1,100 patients and 4,000 medical personnel and family members from four downtown New Orleans hospitals in less than 36 hours. This ' morphed into a grassroots volunteer search and rescue organization that has deployed to rescue people during, and other natural disasters.Numerous articles have been published in fire-rescue trade journals such as and describing the advantages, capabilities, and benefits of using airboats for water rescue operations, and providing in-depth description of actual water rescue incidents, including the flooding of New Orleans.Airboats are particularly effective at water rescues in shallow, marshy, or icy winter environments. Airboats are partially and can therefore navigate effectively over obstacles, such as partially submerged buildings and wreckage or, that would stop a normal boat. In ice rescues, use of airboats cuts the average rescue time from 45 to 60 minutes to seven to 12 minutes, according to data from Minnesota fire departments. They are also faster, larger, safer, and more durable than other small boats used in ice rescues.Though airboats are highly effective at water and ice rescues, airboats and do not work well together. Rotor wash from low-flying helicopters can push and even capsize airboats. During post-Katrina rescue operations, a helicopter's rotor wash was reported to have capsized one airboat, and many airboats were blown into the sides of buildings, standing utility poles, and bridge pilings by low-flying helicopters.
US Special Forces Aircat airboat in VietnamDuring the the airboat was used by and to patrol riverine and marshy areas where larger boats could not go. Two of these airboats were also used by the after they were captured from the U.S. Special Forces by the (PAVN) in September 1967.Airboats are also used in Texas and Iraq for border patrol. The airboats used in Iraq were supplied by American companies and assembled in Iraq by American civilian contractors, and they are used by both American and Iraqi forces to patrol the Tigris and Euphrates rivers, the of southeastern Iraq, and the waterway, the latter two of which include parts of the Iran-Iraq border. Modern Iraqi military airboats are 18 feet (5.5 m) long, powered by 454 hp engines hooked up to 78-inch (2.0 m) Whirlwind propellers, and armed with crew-served machine guns.
The Nov/Dec 2007 issue of had an article on airboats used in Vietnam and in Iraq and has had numerous articles on airboats used by U.S Coast Guard and other state and county units for rescue of and rescue in floods or after hurricanes.In 2013 the purchased 20 airboats for use as personnel transport, patrol, and cable laying and light cargo boats in the rivers and marshes of Iraq. See also., a similar type of vessel using a vertical 'pipe' to propel the airNotes. In early history the term airboat was applied to or, i.e. Capable of taking off and landing on water surfaces. Early airboats were known as 'hydroglisseurs' (airboat in, lit. 'water slider'), hydroplanes, hydrofoils, or other names.
Flying (1915-1916) and Cercle du Mononautisme Classique (in French). The source cited states the price of an airboat as $25,000 to $40,000 in 2004, which is equal to between $33,000 and $53,000 in 2018 dollars. Lambert refers to their manufacturer, the company of France, and 'Hydro-Glisseur' means 'airboat' in.References.
