"The Sea Lion was never intended as a novelty or a gimmick. Instead, Witt and SeaRoader Aquatic built it to be a performance-first amphibious machine capable of excelling both on asphalt and in open water. Its core is a Mazda 13B 1.3-liter rotary engine, a powerplant well-known among enthusiasts for its high-revving characteristics and compact form factor. The choice of rotary power gave the Sea Lion the ability to stay lightweight while still delivering respectable power output."
"The intersection of automotive engineering and marine innovation has always produced fascinating machines, and few embody that better than the 2012 Sea Lion Amphibious Prototype Car. Originally built by Marc Witt and the team at SeaRoader Aquatic, this one-off vehicle was touted at its debut as the fastest amphibious car in the world. Over a decade later, it's resurfacing as a collector's dream, heading to auction via Mecum on September 20th."
The 2012 Sea Lion Amphibious Prototype Car is a one-off, performance-first amphibious supercar built by Marc Witt and SeaRoader Aquatic and later headed to a Mecum auction on September 20th. The vehicle uses a Mazda 13B 1.3-liter rotary engine to maintain a lightweight, high-revving powerplant. The body comprises CNC-milled and TIG-welded 5052 aluminum panels around a central monocoque for rigidity and corrosion resistance. Front wheels retract hydraulically for a cleaner hull profile, and water propulsion is provided by a modified Berkeley 12 JC jet drive pump. The design balances aerodynamic and hydrodynamic requirements for smooth transitions between road and water and appeals to collectors.
