When the still-somewhat confidential Feadship Project 710 yacht starts sea trials soon, she’s mark a significant first for the shipyard. She’ll further mark a significant first for yachting. The diesel-electric superyacht will see her gensets running on biofuel, greatly reducing emissions. Further noteworthy, the owners will take delivery with the same biofuel in the tanks.
It’s all part of the original design brief, in which the owners wanted yacht questioning common design and engineering practice. That explains the reliance upon HVO, a.k.a. Hydrotreated Vegetable Oil, as the biofuel. It’s a direct replacement for diesel, meaning there’s no need to adapt systems, fuel lines, or other components. (Ethanol, widely available for years in some diesel to reduce carbon emissions, dries out rubber components and dissolves resins in fiberglass, among other issues.) According to Feadship, when Project 710 burns it, total carbon-dioxide emissions will drop by approximately 90 percent.
Additionally, the megayacht, with a single-level engine room, employs Feadship’s own electrical drive system. This replaces traditional drive shafts and rudders, instead relying upon electric contra-rotating thrusters from Veth. Notably, the Project 710 yacht’s electrical storage capacity is four and a half times that of Savannah, Feadship’s first hybrid yacht.
Yet another technical highlight of the new launch is how waste heat is recaptured and utilized. Waste heat is the normal warmth from mechanical systems, including ones supplying creature comforts. Typically, it escapes into the air, therefore earning the “waste” designation. Since superyachts‘ hotel loads consume significant fuel (from diesel gensets), Feadship’s engineers determined they could capture the waste heat from not only the Caterpillar gensets, but also the air-conditioning system’s chiller. This heat in turn benefits the water flowing from faucets, the pool, and even the air-conditioning system, among other items aboard. The yacht also uses a heat pump to extract heat from the surrounding sea water.
Once she begins cruising, a party of 14 will enjoy what Feadship says is a bold, contemporary ambience from RWD and Monk Design. The latter’s principal has an extensive design background in the automotive and yachting industries. The studios, and therefore the owners’ party, have far more relaxation and entertaining space to tailor due to the above-mentioned single-level engine room. Some of the Project 710 yacht’s amenities include a bow observation lounge (below), with double-curved glass from floor to ceiling. A semi-submerged lounge, of course with observation glass, sits back aft. Speaking of glass, glass balustrades on various decks preserve the views from inside. Finally, an asymmetrical atrium stairway takes guests to an unexpected dining area below decks. Just above the waterline, it’s adjacent to a slide-open door.
Feadship intends to reveal more information about the megayacht in the coming months.
