Several units of the Arc Sport were already afloat 16 months after the start of the project. This was made possible by the company's own 14,000 square metre production facility in Los Angeles and a team of former SpaceX engineers. The software is written in-house, and the development department comes up with plans for the battery packs, temperature monitoring and the drive train.
Wakesurfing on the stern wave of the Arc Sport
There was one important requirement for the seven-metre-long ARC Sport: a stern wave that is suitable for wakesurfing and wakeboarding and that corresponds in size and shape to that of combustion-powered boats. Since only resistance, ergo displacement, creates waves, the aim was to utilise the weight of the batteries (226 kWh) to advantage. Almost a tonne of computer-controlled water ballast is added to the stern of the 3.1-tonne vessel, while two wings amidships and three tabs in the stern shape the waves.
For wakeboarding with a leash, the tower can be lowered depending on your riding ability. For speeding, it can be lowered completely together with the hardtop - a good prerequisite for getting into the hulls of large yachts. Apart from the output of the 370-kilowatt electric motor, Arc does not provide any further technical details, but does state the starting price: 236,000 euros, including bow thruster.
