Founding and the High Speed Amphibian idea
Alan Gibbs is a New Zealand businessman. He told Powersports Business that his interest in amphibians began with a practical problem: his farm in New Zealand borders a tidal area up to a mile (1.6 km) long that he wanted to cross [3]. The company says it has worked on High Speed Amphibian (HSA) technology since 1994, although a 2012 company release dates the start to 1996 [6][1].
Engineer Neil Jenkins, who had worked in the automotive and aerospace industries, joined about 15 years before 2012 and merged his own firm, Krafthaus, into Gibbs Technologies [3]. A September 2012 company release names Gibbs and Jenkins as the founders, and both 2012 releases name Jenkins as chairman [1][2].
Gibbs designs use a planing hull, lift their wheels clear of the water and drive a water jet, so they can run fast on water as well as on land [4][7]. The company says it was the first to build fully road-approved vehicles that exceed 30 mph (48 km/h) on water and change between land and water in under 5 seconds [6]. Its patents cover wheel retraction, engine cooling, powertrain, hull design and shared land and water controls [10]. A US patent granted to Gibbs Technologies in 2008, for example, covers a suspension that swings an amphibious vehicle's wheels up into a marine position and back down for land use [8].
Aquada and the Channel crossing
The first Gibbs vehicle was the Aquada, an open sports car introduced in 2003 [6]. It used a Rover V6 of about 175 bhp and a Gibbs water jet, reached about 30 mph (48 km/h) on water, and was priced at about £150,000 at the time [4]. On 14 June 2004 Richard Branson drove an Aquada from Dover to Calais in 1 hour 40 minutes 6 seconds, a record for an amphibious vehicle at the time [4].
The Aquada never became a high-volume product. New Atlas reported that Gibbs had first aimed at amphibious cars but ran into the passenger-car safety rules that road cars must meet, which pushed it toward ATVs and motorcycles, where the rules are lighter [5]. The company says only a small number of Aquadas were offered to collectors [12].
Michigan and the Quadski
By 2012 the business was run from Auburn Hills, Michigan. In June 2012 Gibbs Technologies Inc. changed its name to Gibbs Sports Amphibians Inc., with nearly 100 staff [1]. In September 2012 it announced a 54,000 sq ft (5,000 square meter) factory in Auburn Hills to build the Quadski, said more than $200 million had been spent on HSA research, and described two divisions: Gibbs Sports Amphibians for consumer vehicles and Gibbs Amphitrucks for commercial, first responder and military vehicles [2].
The Quadski, an amphibious quad bike with a top speed of 45 mph (72 km/h) on land and water, went on sale through powersports dealers for about $40,000 [2][3]. The company says about 1,000 Quadski and two-seat Quadski XL units were built before production ended in 2016 [7].
Gibbs also showed larger amphibious trucks, the Humdinga and the Phibian, aimed at rescue and patrol work, and in 2014 Fox News reported that Singapore's ST Kinetics would build the Humdinga under license [3][13]. In October 2015 it showed the Biski amphibious motorcycle and the three-wheeled Triski as concepts, looking for a powersports maker to produce them [5].
Status today
No Gibbs model has been in series production since the Quadski ended, in the sources found [7]. Gibbs Amphibians in New Zealand supplies parts and technical support for existing Quadskis, and its Quadski site says work on a next-generation amphibian continues [7].
In September 2022 Hilco Streambank, a firm that sells intellectual property, announced that an amphibious vehicle patent portfolio, with design files, test data and more than a dozen trademarks, was available for sale or license, citing more than $200 million of development spending [9]. Hilco's listing identifies the portfolio as Gibbs Amphibians' and names the Quadski, Aquada and Humdinga as vehicles brought to market [10]. The Gibbs website continues to offer its eight vehicle platforms for license, case by case [11]. No sale of the portfolio had been reported in the sources found.
