Let me put it this way: These boats, makes the usual (and not at all cheap) yachts to look usual and cheap. Take a look the following images, and decide which one will you get for yourself (one day)...
Contestant #1 : This 508-feet yacht is designed to look like a section of the The Principality of Monaco. It has 4 main decks (and lots more beneath) with casino, swimming pool, a waterfall and a grand atrium with seven guest suites. And.. let's see, what else exists in Monaco? Oh yes, an F1 racetrack. Yes indeed, it carries an F1 racetrack. This yacht gets the title "Overkill", for reasons that need no further explanation. [Source]
Contestant #2: This yacht with the name Breathe, is designed following nature's patterns mostly, to solve mechanical problems. But most of all, it is inspired by the stripes of a zebra. These stripes are said to be a natural cooling mechanism. The variations in temperature due to the different amount of heat absorbed by the stripes, are believed to create an air current that naturally cools the animals. Aboard the yacht, light hulls, dark funnels and glass shells are designed to produce a consistent flow of air on the outside decks. This reduces the amount of power needed for air conditioning. This yacht gets the title "Inspired". [Source]
Contestant #3: This 144-foot Catamaran has zero carbon footprint, because it is designed to harness energy from various sources, such as solar, wind and waves. According to the designers, this is the world’s first totally self-sufficient zero carbon LSV. What this simply means, is that it can (always theoretically) stay at sea indefinitely. The title that this boat gets is "Forever young" [Source]
Contestant #4: This thing is for real. Its the world's largest solar-powered boat in world record circumnavigation attempt. It began its long journey around the globe on September 27 (last year), using only solar energy. The two carbon contra-rotating propellers with a diameter of almost two meters each, are powered with four electric motors (two in each hull) having a maximum output of 120 kW. The 31 m (102 ft) long - 15 m (49 ft) wide vessel is covered with 537 square meters (5,78 sq ft) of solar panels, a total of 825 modules equipped with 38,000 individual photovoltaic cells . The electric energy is stored in six blocks, each containing 12 lithium-ion batteries (not like the ones that your phone has). It travels with 14 knots and can host 40 passengers. It gets the title "Green record", first because it is green, and second because it brakes many world records [Source]
Contestant #5: Here comes our last challenger. Is it a bird? Is it a plane? No, its the Terrawind! This amphibious house/car/boat can travel with ease on sea and land, and when the drivers gets tired, he can sleep in it as well. The children can then go fishing, simply by opening their window. No more waiting lines in ferry-boats. This babe gets the title "Transformer". [Source]
