Crystal Cruises' new yacht boasts its own submarine

Are you ready for your sub-aquatic cruise adventure?

That's the question Crystal Cruises poses with its new Crystal Esprit luxury yacht, which will begin sailing in the Seychelles near Madagascar next week. The 62-passenger yacht, far more intimate than Crystal's 1,000-passenger cruise ships, features among other water toys its own 2-person submarine.

The sub is built by U-Boat Worx, a 10-year-old Dutch company that specializes in tourist submarines. Crystal has a C Explorer 2 model, which is rated to a depth of 100 meters. A large acrylic bubble provides 180 degree visibility while a 21.6 Kilowatt hour lithium ion battery provides the power.

Prices for the U-Boat Worx subs range from around $360,000 for a 1-person model to upwards of $1 million for a 5-seater.

On Crystal, excursions will cost $599 per person for a 30-minute ride.

For those on a budget, Crystal Esprit's other water toys include water skis, a wake board, two types of ocean kayaks, jet skis, Zodiac-style boats, as well as fishing and snorkeling gear — all complimentary.
