The Adastra represents the future of luxury yachts in style and fuel consumption (it can travel 4,000 nautical miles without refuelling). The unique exterior conjures up images of a futuristic spaceship, while the interior - inspired by Scandi and Asian design - looks fit for a party in outer space. Oak panelling runs throughout and natural light streams in from the wrap-around windows - of course, there's a sauna and whirlpool. Did we mention that it can be controlled by an iPad from 50 metres away?

Spanning an impressive 163 metres, Eclipse is the second largest yacht in the world, sleeping up to 36 guests and 70 crew members. Aboard you will find a gym, jacuzzi, beauty salon, indoor garden, cinema, and sauna. There's not one but two helipads, and if you happen to find yourself engaged in a little sea warfare, you're all set because it comes fully equipped with a missile system. But what makes Eclipse truly special is its pool. At 16 metres, it is the largest pool on any yacht. But as the saying goes, it's not the size that matters but what you do with it… At the touch of a button, the bottom of the pool raises and transforms into a dance floor. Ta da.

One of our favourite architects, the late Pritzker prize-winning Zaha Hadid, collaborated with shipbuilders Blohm+Voss to create a super innovative super yacht concept: step forward, Unique Circle Yachts. The largest of the fleet, Unique Circle, is over 128 metres long and has an underwater viewing platform. Like Hadid's other architectural designs, they're pretty daring feature fluid, interconnected lines over traditionally rigid designs. The yacht's exterior is all curving shapes which overlap and connect to different decks, evoking the skeletal structure of natural marine formations. If you've ever wondered what it's like to float inside of a seashell, here is your chance. Rumour has it that Blohm+Voss are still looking for a buyer to fulfil the concept. Better get your chequebook out…

Sea Force One is the ultimate party boat. The DJ booth, LED lighting, black-leather seating, fur sofas and fully stocked bar on the upper deck will make you feel like you're in a nightclub rather than in the middle of the ocean. The circular dining area on the main deck offers sensational views and is perfect for dinner and drinks before dancing the night away. The illuminated staircase creates a waterfall-effect which is sure to give you a dramatic entrance every time, while luxurious loungers on deck are the ideal place to nurse a hangover. Alternatively, head to the state-of-the-art gym to sweat out the alcohol. Now that you have the perfect party location, the tough part is deciding which of your ten friends to take with you. Just try not to fall overboard…

As the name suggests, Diamonds Are Forever is truly grandiose. The interior design will make you feel like a prince/ss on a floating sea palace. Crystal chandeliers and 24K gold accents can be found in almost every room, while the master suite is decked out with marble columns and hand-painted sky murals. Diamonds Are Forever doesn't scrimp on amenities either. It has an exceptional kitchen with a large walk-in fridge and freezer, sound-proof doors, jacuzzi, sauna, massage room, helicopter pad and gym. Climb up to the top sundeck for sweeping views of your sea kingdom.

If you've been to the Cannes Film Festival, you'll have heard of the Octopus. This impressive super yacht belongs to Microsoft co-founder Paul Allen and is the venue for his annual Cannes Film Festival party. Features include a cinema, gym, glass-bottom pool, basketball court, two helicopter landing pads and a recording studio used by Mick Jagger. What's more is that the yacht comes with a ten-person submarine for making a stealthy and stylish getaway à la James Bond. With all of this on-board, it's no wonder Paul Allen's annual Cannes Festival party is one of the most hotly anticipated events of the year.

Numptia is ideal for those after some R&R. The warm colour palette with its reds, browns and whites and plush seating area adorned in the finest cashmere and velvet, creates an extraordinarily comfortable and tranquil lounge room. After a long day of tanning, unwind here while watching your favourite films on the 103″ Panasonic television screen. If you need pampering, head to the yacht's fully equipped state-of-the-art spa where you'll find a Turkish bath, hair salon, massage room, beauty room and sauna. After a week on the Numptia, you'll leave feeling rejuvenated and replenished. Unfortunately, we can't say the same for your wallet.

The luxury superyacht Dubai has it all. At 162 metres, it's one of the world's largest private yachts and can accommodate 115 people. Dubai has seven decks, a variety of formal and informal saloons inside and out, three elevators, multiple hot tubs, a gym, a squash room and a spa. The striking interior features a glass circular staircase which changes colours every time pressure is applied, making you feel like a giddy five-year-old all over again, while the foyer is completely done up in mosaics.

This is one of the most extravagant superyachts out there. Everything from the lighting, accessories, fabrics and furniture was made and designed by the fashion house Fendi. And believe us when we say that absolutely no expenses were spared. For one, the lift is plated in 24K gold. On the outside deck, circular daybeds with silk pillows surround the custom-made hot tub. If you tire of admiring the ritzy beauty of Lady Luck, you can work up a sweat in the air-conditioned gym or built-in sauna.

If you think superyachts couldn't get any more ludicrous, you haven't seen Streets of Monaco. This is the first design proposal by Yacht Island design. Their concept is relatively simple: to create a floating city. On the outside decks, you will find scaled reproductions of famous landmarks in Monaco like the Monte Carlo Casino, Hotel de Paris, Café de Paris, La Rascasse, Loews Hotel and a fully functional go-kart circuit based on the Monaco Grand Prix. Inside is an oasis with palm trees, multiple water features, a café, and hundreds of lounge chairs. If this isn't enough, you will also find a full spa with manicure and hair salons, gym, massage suites, wine cellars, private lifts, dance hall and a casino. You'll have to wait for this floating city as it isn't scheduled to be built until 2017. The asking price? $1billion. But six months should be plenty of time to save, right?
