The most impressive eco-powered yacht is still Savannah, the 83.5 m Feadship hybrid with a 1 MWh battery. We ranked 9 luxury eco-power yachts by size, from superyacht hybrids to solar-electric catamarans you can order today. Four entries from our old 10 could not be verified and were dropped, so the title is now 9.

1. Savannah (Feadship): 83.5 m hybrid superyacht, 1 MWh battery
Savannah was built in 2015 at Feadship in Aalsmeer. A single diesel engine, three generators and a battery bank drive a hybrid electro-mechanical platform that offers fuel savings of about thirty percent, and the battery is a 1 MWh unit from Corvus Energy.
She won Motor Yacht of the Year at the 2016 World Superyacht Awards and has appeared as a film location.
How we valued it: Largest hull (83.5 m) and battery. She is a one-off, so there is no list price.
2. Ethereal (Royal Huisman): 58 m hybrid performance ketch
Royal Huisman calls Ethereal the first hybrid superyacht, launched in 2008 and delivered in 2009. Her drive train recharges a lithium polymer battery bank under sail, and the same batteries can run the whole boat in near-silent mode.
The yard cites different battery figures over the years (400 kWh in one report), so we leave the exact number out.
How we valued it: Second-longest, and the original. No price is public.
3. Rainbow (Holland Jachtbouw): 40 m J-class sailing yacht
Rainbow launched in 2012 as a replica of the 1934 America’s Cup defender. The yard developed a full hybrid system with WhisperPower, replacing the usual engine and generator layout, and the yacht can run entirely on lithium batteries overnight.
A 2014 listing claimed fuel savings of up to 30 percent. She has since been offered for sale through brokers.
How we valued it: Third by length, about 40 m.
4. Tûranor PlanetSolar: 31 m solar catamaran, 537 m² of panels
The largest solar boat in the world was launched in 2010 and in 2012 became the first solar vehicle to circle the globe, a 584-day voyage. Construction cost €15 million.
The ship has changed hands and names, and in September 2022 she ran aground in India and was heavily damaged. She was relaunched on 23 May 2025 in Kaohsiung, Taiwan as the Porrima P111.
How we valued it: Placed by size; the €15 million build cost is the only price we can verify.
5. Arcadia A85: 85 ft solar and hybrid yacht
Arcadia’s first model launched in 2010 with solar panels and a diesel-electric hybrid system, and it can cruise silently on electric power at up to 8 knots. Listings for a 2024 A85 mention roughly 40 m² of solar panels.
The smaller Arcadia Sherpa offers a similar zero-emission option.
How we valued it: Placed by model length, 85 ft. No list price was found.
6. Silent Yachts SY80: 24.4 m solar-electric flagship
Silent launched its SY80 flagship at the Fano yard in summer 2025 and won Best Electric Catamaran at Cannes that year. Sources agree on a 22.4 kWp solar array and a 12-knot top speed, but battery figures range from about 354 kWh to 708 kWh.
There are two-deck and three-deck layouts for up to 12 guests.
How we valued it: Sits here by length. Battery spec varies by source, so we avoid one figure.
7. Silent 62 3-Deck: all-electric solar catamaran, 17 kWp array
The Silent 62 uses a 17 kWp solar array with a diesel generator as a reserve. One broker listing quotes delivery in 14 to 18 months.
How we valued it: Model size decides the slot; no price verified.
8. Sunreef 60 Power Eco: solar-electric catamaran
Up to 68.6 m² of integrated panels, two 180 kW electric motors and a 250 to 320 kWh battery bank. It has won a World Yachts Trophies award.
How we valued it: Slotted by model size, 60 ft; no price found.
9. Greenline hybrids: the most affordable on this list
Greenline built the first serial-production hybrid powerboat, the 33 foot Greenline Hybrid 33 in 2009. As of 2024 the yard offered eight models from 39 to 58 feet.
A 2026 Greenline 42 Hybrid new unit was listed by one US dealer at $1,414,875, an asking price, not a list price.
How we valued it: Smallest hulls, but it is the only entry with a dealer price.
