The world's most eco-focused yachts

From hybrid engines to high-tech wastewater treatment, new developments in naval architecture and design are helping superyachts reduce their environmental impact. BOAT discovers the innovative technologies behind the world's most eco-focused superyachts.

Bravo Eugenia

The 109 metre Bravo Eugenia is highly efficient despite her impressive size. The Oceanco-built superyacht is powered by a hybrid propulsion engine that offers a quiet electric mode and which allows her to consume 30% less fuel than other motor yachts in her size class. She is also equipped with a waste heat recovery system and an integrated battery for optimal operation and performance.

Yersin

The 76.6 metre Piriou explorer yacht Yersin, which has been classified as a Bureau Veritas Clean Ship and boasts a 15,000 nautical mile cruising range, was designed by Pierre-Jacques Kubis for private discovery voyages and has also been chartered for scientific expeditions led by the Monaco Exploration Society. The yacht was constructed from 95% recyclable materials, including recyclable resin decks that substituted wood for a more sustainable alternative. To minimise its impact, Yersin’s ice-classed hull has been coated with a non-biocide silicon antifouling layer while the yacht's dynamic positioning minimises the impact of the anchor when dropped. Additionally, Yersin is equipped with filters on all engines that reduce NOx and SOx emissions by 99.8% and retain 99.8% of soot particles.

Artefact

Francisco Martinez

An early adopter of the International Maritime Organisation’s Tier III emissions regulations, Artefact features solar panels and a wastewater recycling system, as well as a large battery storage system, which means the yacht can at times operate completely independently of internal combustion engines. Although  Artefact is a sizeable yacht measuring 80 metres with a volume of 2.999 GT, the yacht is incredibly silent, extensively soundproofed and equipped with custom six-bladed propellers that minimum noise pollution and vibrations while at sea. Part of what contributes to the yacht's quiet cruising is its hybrid diesel-electric system that integrates lithium batteries and which the builder, ABB, says saves 30% of energy and emissions.

Delivered by Tankoa in 2018, the 72m Solo was one of the first yachts afloat to comply with the International Maritime Organisation’s Tier III regulations that were introduced to limit emissions and water pollution. The eco-friendly superyacht was also awarded the Green Plus Platinum notation, the highest level of environmental certification from the RINA society.

Exuma

The 49.5 metre explorer yacht Exuma boasts a number of accolades for her design. Among others, this Perini Navi superyacht was honoured with a RINA Green Plus Award upon its launch in 2010. Designed by Vitruvius and naval architect Philippe Briand, Exuma features an all-aluminium hull with a uniquely styled bow that slices through the waves with ease and enhances fuel efficiency by up to 30%.

Heesen superyacht Home pairs a state-of-the-art hybrid propulsion system with a proven Fast Displacement Hull Form by Van Oossanen Naval Architects to reduce its environmental footprint and improve efficiency. Designed as a home on the water by Omega Architects and Cristiano Gatto, the 50 metre Home is 48% more efficient than other yachts of its size. The yacht can cruise in four different modes depending on the situation; an “eco mode,” a “quiet mode” using electric motors and reducing sound pollution and a "diesel model" for cruising quicker passages. The final feature is the special “boost mode,” which combines diesel and electric for added power on the water.

Bintador

Another eco-focused yacht by Tankoa, the 50-metre Bintador was launched in 2019 and features a hybrid-propulsion system courtesy of hybrid specialists e-Motion. Using traditional propulsion under the power of twin MTU 8V 4000 M54 engines, Bintador can reach a speed of 16.5 knots, topping out at 18 knots when switching to “boost mode” which combines the power of both MTU engines and her 300kW electric motors. When speed is not a requirement, Bintador can change down into her "diesel-electric" and "hybrid" modes, which are significantly more eco-focused and more fuel-efficient than a traditional superyacht engine system.

Luminosity

Despite measuring 107 metres LOA and with a volume of 5,844 GT, the newly-launched Benetti yacht Luminosity features a unique diesel-electric propulsion system with clean exhausts and a battery bank for up to 12 hours of silent operation at anchor. A considerable engineering feat, Luminosity runs on six 1,000kW generators that power two Azipods to help reduce fuel consumption by as much as 20%.

Black Pearl

Black Pearl features controllable pitch propellers that feed power back into the ship via a pair of shaft generators, providing enough power to support the yacht's hotel load. Energy is saved at every turn on board the 106.7m sailing superyacht, from the HVAC system to her advanced DynaRig sails that allow Black Pearl to take advantage of the eco-friendly natural resource of the wind.

Savannah

The 83.5m Feadship yacht Savannah uses the Dutch yard's pioneering Breathe propulsion system - which allows for five different operation modes from diesel and diesel-electric combinations to fully electric. Power comes from a 30-tonne lithium-ion battery bank capable of holding a million watts of electricity. But even in diesel mode, Savannah is highly efficient, with 30 per cent lower fuel consumption than her contemporaries thanks to her dynamic hull shape and steep entrance angle.
