The Sea Lion automotive name might have been nabbed by modern-day electric vehicle maker BYD but, back in 2012, it was aptly used on the remarkable creation you see pictured here – which was once fantastically described as ‘the world’s fastest amphibious car’.
The Sea Lion is just one of the 275 lots of cars and motorcycles and 1000 lots of automobilia being dispersed from the estate of the late Larry Klairmont, a decorated WWII marine who went on to make his fortune in property cleaning and real estate.

Clearly a fan of the unusual, his collection also includes a 1990 Pulse Litestar Autocycle (think: jet-fighter cockpit on wheels), a Pebble Beach concours-winning Rolls-Royce Phantom III with aerodynamic bodywork and a 1956 Continental bubble top custom car with a Perspex canopy roof.
But the Sea Lion is probably the most far-out vehicle of all, being made from CNC milled, TiG-welded aluminium and with front wheels that are hydraulically drawn into the arches to reduce drag in the water.

A modified Berkeley jet drive propels the Sea Lion through the water at up to 60mph

The car also features retractable sidepods for both storage and flotation and a supercharged 1.3-litre Mazda rotary engine that connects to a jet drive for amphibious use, with the car/boat being driven by a joystick when on the water. Described by Mecum Auctions as a prototype, it was designed and built by Californian boffin Mark Witt and has a claimed top speed of 180mph on land and 60mph on the water. Witt offered it for sale in 2012 through specialist car dealer Fantasy Junction, when it had a price tag of £160,000 – and its voyage began.
It gives a whole new meaning to the idea of a car that handles like a boat.
