Editing Amphibious vehicle (section)

====Boats====
Some amphibious vehicles, rather than being designed for land transport with the ability to cross water, are designed as water-transport vehicles with the ability to travel on land. The distinction is that the vehicles are designed to be high performing on water, with the land transport ability added to give additional functionality, rather than being the main function. [[Sealegs Amphibious Craft]] are an example of this, which are a range of aluminium three-wheeled fabricated boats (mostly [[Rigid-hulled inflatable boat|RIBs]]) designed and manufactured in [[Auckland, New Zealand]] since 2005. These craft can travel up to 39 knots on water, but travel at only 7.5&nbsp;km/h on land, showing the preference for water performance in design. Various versions of this type of amphibious boat design have been produced, including the French [[Iguana Yachts|Iguana Yacht]], an amphibious [[motorboat]] featuring all-terrain [[Continuous track|tracks]] (covered in the "Tracked" section below).

Recently,{{When|date=June 2021}} Gibbs Amphibians has developed a new type of amphibian, one capable of high speeds on both land and water. The vehicles use a patented hydraulic system to raise the wheels into the wheel wells, allowing the vehicles to plane on water. These vehicles can transition between land and water modes in about five seconds. The first Gibbs fast amphibian is the [[Gibbs Quadski|Quadski]], introduced in October 2012. It went on sale in January 2013.{{Promotion inline|date=June 2021}}

=====Oyster boats=====

Since 1977, several boat builders in Brittany have built specialized amphibious vehicles for use in the area's [[mussel]] and [[oyster farming]] occupations. The boats are made of aluminium, are relatively flat-bottomed, and have three, four, or six wheels, depending on the size of the boat. When the tide is out the boats can run on the tidal flats using their wheels. When the tide is in, they use a propeller to move through the water. Oyster farmers in [[Jersey]] make use of similar boats. Currently, ''Constructions Maritimes du Vivier Amphibie'' has a range of models.<ref>{{cite web  |url=http://cmv-amphibie.com/en/ |title=Our projects |website=CMV Amphibie |access-date=13 May 2018}}</ref>
