The idea behind the 108M is to appreciate the natural beauty of a sea voyage, rather than load up the yacht with a bunch of attention-getting opulence that’s distracting at best and inefficient at worst. Efficiency is also given a high premium, as the 108M is described as a “hybrid mega yacht” at Hareide’s official site, with two energy sources depending on the intended use of the craft: Passengers on board the 108M won’t exactly be roughing it, however, with access to an elevated dining area and observation space, a 20-meter swimming pool surrounded by a “tranquil garden,” and a multi-use grand hall with views and contact with nature not possible on a traditional yacht. That is, they will, should the 108M ever escape its conceptual prison and become a reality. In the meantime, you will have to struggle to appreciate nature the old-fashioned way: On your lumbering, energy-inefficient luxury mega yacht.
