Here it is, the world’s most expensive yachts:

10. $90 million – Le Grand Bleu

From one Russian billionaire to another, the 370-foot Le Grand Bleu was reportedly gifted to Eugene Shvidler from its previous owner, Roman Abramovich. Built in Germany’s Vulkan yard and launched in 2000, Le Grand Blue is grand indeed, setting out with a pair of 3,600-horsepower Wärtsilä engines, a crew of 50 and an onboard 74-foot sailboat and 67-foot speedboat.

9. $100 million – Tatoosh

The 301-foot Tatoosh is owned by Microsoft co-founder Paul Allen, a secretive kind of guy, who is said to bar reporters from coming aboard. The mega-yacht supposedly has its own theater, swimming pool and lobster tank and has landing pads for two helicopters.

8. $103 million – Annaliesse

Three dozen guests can spread out in the 280-foot Annaliesse’s 15 staterooms, a mega-yacht that treats cruisers with marble columns, its own “full-service” spa, salon, library, children’s play area and movie theater with a 100-inch screen. The master stateroom has a king-size bed and remote-controlled panoramic windows.

7. $116 million – Alysia

The 280-foot sister ship of the Annaliesse, the Alysia is the slightly prettier of the pair. The ship’s 1,300 square-foot master stateroom comes with its own private deck, jacuzzi, marble decked bathroom and California king-size bed. Elevators whisk guest through five decks, which include a sundeck with barbecue, a bar, an 8-person hot tub, spa, gym, salon and a 500-bottle wine cellar. Can’t stand the wine, pampering, massages and endless tanning? — make an underwater escape with a pair of “scuba scooters.”

6. $129 million – Ecstasea

Another toy of Chelsea Football Club-owning Roman Abramovich, the 250-foot long Ecstasea was built with an Asian-inspired interior theme, complete with bamboo furniture. The ship’s walls are paneled with carved cherry and guests pad around on marble flooring. Onboard, a disco, sauna and Turkish bath greet guests, who can arrive or depart from either retractable helipad.

5. $130 million – Pelorus

Oh, Roman… how can thee outdo thine self? Pool — check. Helipads — a pair. Staff? — 40, including a few from Britian’s SAS. Mini-submarine — aye-aye. Missile detection system? — why not!

4. $200 million – Octopus

Another Paul Allen project, the Octopus is a 416-foot sea beast tamed only by a crew of 40, some of which are said to be ex-Navy Seals. The ship hosts seven smaller boats, two helicopters, a 10-person submarine and like a luxurious Kraken, the Octopus lashes out at the sea with a robotic submersible, which scours the ocean floor.

3. $200 – Rising Sun

A yacht so beloved, it comes with its own fan site! The 453-foot Rising Sun is co-owned by Oracle CEO Larry Ellison and famed producer David Geffen. The five-story boat has 82 rooms and more than 24,000 square-feet of living space. Highlights include onyx countertops, 9,900 square-feet of teak-layered decking, a movie theater and a basketball court/helipad.

2. $210 million – Lady Moura

At 354-feet long, the Lady Moura is a big woman built in 1991 by “order” of Saudi Saudi Prince Nasser al-Rashid. So large it has trouble entering the harbor of Monte Carlo, the mega-yacht reportedly has a crew of 60, a pool with a retractable roof and its very own mock beachfront complete with sand. The yacht made its biggest wave in 2007 when it ran aground at that year’s Cannes Film Festival.

1. $350 Million – Dubai

Owned by Sheikh Mohammed bin Rashid Al Maktoum, the ruler of Dubai, the 531-foot Dubai has interiors designed by Philippe Starck, space for 115 guests and 88 crew members, six guest suites and five VIP suites — all with open balconies. Interior spaces are channeled towards a “massive” foyer and atrium that connects each of the mega-yacht’s eight deck. Outside, the ship hosts a large pool, squash court, helipad and a small aircraft hanger.
