Feadship is marking its diamond jubilee with a new marine gem.

The Dutch shipyard has designed a 246-foot superyacht in honor of its 75th anniversary. The newcomer has been christened C after the element carbon. Represented by the letter C on the periodic table, carbon is the basis of diamonds, and diamonds are the basis of Feadship’s new concept.

Designed by Ruud Bakker and Tanno Weeda, C features a dazzling, angular exterior with facets that catch the light like the cuts on a sparkling diamond. These facets coupled with expanses of glass ensure the interior of the yacht is filled with an abundance of natural light, creating what Feadship describes as a “light-filled gallery and unprecedentedly fluid living space.” The forward and aft section of each deck is also offset by a half-level, further increasing the fluidity and flow throughout.

At the center of the C lies an atrium with floating stars and a lift without walls that allows seafarers to navigate decks in a novel fashion. Highlights of the living quarters include a duplex owner’s suite, a partially enclosed sea lounge that can be used at anchor or on the waves, a beach club with a sea-level dining area, and a private observation deck with an articulating crow’s nest. To top it off, C is outfitted with two infinity pools that match the hexagonal shape of the atrium and other seating areas.

C also shines on the technology front. She features a sleek hull and a fully electric propulsion system similar to sisterships Breathe and Savannah that renders her 30 percent more efficient than a typical 246-footer with dual shafts, propellers, and rudders, according to Feadship. Her streamlined underwater profile means less wake, too.

C will also be equipped with fuel cells and lithium-metal batteries that will together cover all power needs. (Feadship has also incorporated fuel cells on Project 821.) Green methanol will be the fuel of choice due to its relatively high density and ease of use. Normal cruising speed on the fuel cells is 14 knots, while a top speed of 17 knots can be achieved by adding the battery power. In addition, two wave-actuated fins can generate enough grunt to cover one-third of the hotel load.

Another standout of C is the command center on the lower deck. This innovative hub, which has already been rolled out on sistership Ulysses, includes the latest in intelligent situational awareness technology to make navigation and operation a breeze.

C will be fully unveiled at the Monaco Yacht Show next week. The yacht is just a concept at this stage, but Feadship says she is completely buildable. Perhaps the yard will land a buyer in France.
