An inflatable boat is a lightweight boat constructed with its sides and bow made of flexible tubes containing pressurized gas. For smaller boats, the floor and hull beneath it is often flexible. On boats longer than 3 metres/10 feet, the floor often consists of three to five rigid plywood or aluminum sheets fixed between the tubes but not joined rigidly together. Often the transom is rigid, providing a location and structure for mounting an outboard motor. Some inflatable boats have been designed to be disassembled and packed into in a small volume, so they can be easily stored and transported to water when needed. Here the boat when inflated is kept rigid crossways by a foldable removable thwart. This feature allows such boats to be used as life rafts for larger boats or aircraft, and for travel or recreational purposes. Other terms for inflatable boats are “inflatable dinghy”, “rubber dinghy”, “inflatable” or “rubber duck”.
Inflatable boats at Horsea Island, England，Zodiac is a tradename for a make of inflatable boat, but often has become a genericized tradename used to mean any rigid-hulled inflatable boat (RIB).Contents1 Types 2 Repairing 3 Uses 4 History 4.1 Early attempts 4.2 Rubber arrives 4.3 The Titanic and WWI 4.4 World War II 4.5 Modern inflatables 5 Images 6 Rigid-hulled inflatable boat // TypesPVC inflatable with small electric trolling motor Inflatable boats may have rubber floors, either plain or inflatable, or they may include steel, wood or aluminum sheets for rigidity. The tubes are made of rubberised, synthetic sheets of Hypalon or PVC to provide light-weight and secure buoyancy. The tubes are often constructed in separate sections, each with a valve to add or remove air, to reduce the effect of a puncture. Some inflatable boats have an inflated keel to create a “groove” along the line of the hull improving the hull’s wave cutting and turning performance. Due to the lightness, it is easy to cause an inflatable boat to start hydroplaning, thus making it faster than the engine would allow when the hull is operating in displacement mode. A growing use for inflatables is for white water rafting and kayaking, as well as in river, lake and ocean touring. Professional-level rafts and kayaks have existed for many years; since the late 1990s, more affordable inflatable rafts, kayaks (including sea kayaks) and canoes have been developed by European and North American companies. Typically these inflatable boats contain no rigid frame members, so they can be deflated, folded and stored in compact bags. Repairing should a section puncture it can be repaired while still underway.
More extensive inflatable boat repairs – due to pinholes, punctures, peeling, leaks or worn fabric – can be done in dry dock using two-stage synthetic rubber coatings (SRC).Subject to a great deal of wear and tear from the elements – both water and sun – inflatable boats are often replaced when they could be restored or even repaired. Products that aggressively adhere to the damaged Hypalon or PVC shell can fix virtually any surface damage through a unique chemical bonding between the undercoat and topcoat that permanently vulcanizes the two rubber coatings together to make the inflatable as good as new.
However since the Hypalon material increases the cost of the inflatable up to 15% not all manufactures provide the option. Some, such as the Brig and the Zodiac brand inflatable boat offer the option between the PVC or the Hypalon which is recommended for environments of increase heat and sunlight. Uses Inflatables are commonly between 2 and 7 meters (6 to 21 feet) long and are propelled by outboard motors of 5 to 80 horsepower (4 to 60 kW). Due to their speed, portability and weight, inflatable boats are used as:-rescue craft dive boats for scuba diving tenders for larger boats and ships in port and at sea luxury yacht tenders recreational water skiing for racing commercial or recreational fishing for military purposes, such as transporting soldiers from a vessel to shore Inflatables up to 6 meters in length can be towed on trailers on the road. These boats are often used by special-operations units of the armed forces of several nations, for such purposes as landing on beaches or submarines. They have also be used by special operations soldiers without government sponsorship, such as guerrillas, pirates, and terrorists. History Early attempts there are ancient carved images of animal skins filled with air being used as one-man floats to cross rivers. They were inflated by mouth. Sometimes these images have been wrongly described as ancient scuba. In 1839 the Duke of Wellington tested the first inflatable pontoons. Rubber… (And so on)
