Two helicopters and a seven-seat submarine are among the features on the newly announced Scenic Eclipse, a 228-passenger ship being touted as the world's first "discovery yacht." The Eclipse, which is currently being built in Croatia to enter service in August 2018, was designed to further Scenic?s mission to open the private yacht experience so travelers can discover regions previously visited only by the "supremely wealthy or explorers and adventurers." While the ship will hit popular ports in both Europe and the Americas (like Istanbul, Venice, Dublin, and Miami), it will also head to both Antarctica and the Arctic.

Plucky little expedition ships have been plying polar regions since Lars-Eric Lindblad took the first tourists to Antarctica in 1966, but these don?t usually have the level of luxury Scenic plans (which will be akin to Seabourn, SeaDream Yacht Club, or the new Crystal Yacht Cruises). And while the French operator Ponant already sends four large yachts to remote areas, the 16,500-gross-ton Eclipse will be 50 percent larger than those ships while carrying 14 percent fewer passengers.

That difference translates into lots of space, dining options, and a very high crew-to-passenger ratio of almost 1:1. The ship?s all-veranda suites start at a roomy 344 square feet and go up to the 2,500-square-foot, two bedroom Owner's Penthouse Suite, which boasts floor-to-ceiling windows. The yacht also has four lounges, a theater for lectures, three bars, and six dining venues, with food that will range from classic French to pan-Asian fusion. Guests can bliss out in the 5,000-square-foot spa with indoor and outdoor plunge pools and Jacuzzis or work out in the gym with its separate yoga and Pilates studio.

As for the ?discovery? side of things, a team of experts will be on hand to help travelers experience all kinds of adventures utilizing the ship?s zodiacs, kayaks, and scuba and snorkeling gear?and those helicopters and the submarine.

To keep the ride smooth in challenging seas or in big swells when stationary, Scenic Eclipse has custom-built, extra-large stabilizer fins. A dynamic positioning system keeps the vessel in place so there's no need to drop anchor in sensitive areas where the seabed could be damaged. And among a bundle of safety features are two engine rooms, a backup wheelhouse, and a highly reinforced double hull that qualifies Scenic Eclipse for the highest ice-class rating: 1A super.

Founded in Australia in 1986, Scenic is growing fast, with 21 riverboats in Europe, Russia, and Southeast Asia. Scenic Eclipse is its first ocean-cruise vessel, but a sister yacht is planned.

Where exactly will Scenic Eclipse go and how much will cruises cost? Stay tuned. Plans will be revealed in February.
