Project Sea Lion - the world's fastest amphibian vehicle

Monday, May 14, 2012


Each year, amphibious vehicle builders participate in an unofficial competition for the world's fastest amphibious "land speed" vehicle, in what is called Project Sea Lion. This year, the award went to Marc Witt, with his prototype developed beginning with 2006.

Sea Lion was designed using CAD software and spread sheet calculations, by M. Witt. The vehicle is primarily, TIG welded 5052 Aluminum constructed from CNC plasma burned shapes and other CNC milled components. It has an integrated monocoque welded uni-body center section. There are removable side pods, used for floatation and cargo, and removable fenders front and rear.

With few exceptions, there are no structural parts borrowed from other vehicles. The design is created from a clean sheet of paper, and was calculated to exceed previous speed records. When the project began, in 2006, the top water speed was 45 mph and the top land speed was 125 mph. Today, the land speed remains unchanged, but the water challenge has risen to 60 mph.
