Excellence in Electric Boats Under 8 metres / 26 feet: In Production

Cantiere (Boatyard) Ernesto Riva

The Cantiere Ernesto Riva was established in 1771 and this year celebrated the anniversary of two and a half centuries of wooden boat building in Italy’s lake district. Founder Ernesto’s great grandson Daniele Riva is now leading the celebrated boatbuilder into the 21st century with electric boats like the striking and beautifully crafted e-Commuter, which debuted at the Monaco Solar and Energy Boat Challenge in 2018.

In addition to the wooden runabout, their other electric offerings and projects include the Elettra, a classic Vaporini water limousine that transports guests of the Sereno Hotel on picnics and other luxe water outings on Italy’s famous Lake Como.

Freepower Solar Boat,

The Freepower is the creation of Martin Bjurmalm, who named it after his goal of an autonomous boat with the “freedom to go whenever and wherever without fuel stops, with freedom to harvest the energy around us!” He first started thinking about the project when he became a father in 2012 and his thoughts turned to what kind of world we want to leave for our children.

After developing and testing a prototype in 2019, Bjurmalm is now taking orders for delivery of the Freepower in summer of 2022 and interested e-boat and solar investors can take part in the future of the project through a crowdfunding campaign on

Finalists: D3Aak Boat •  Navier 27

Silent 60
Silent Yachts

The founders of Silent-Yachts, Michael and Heike Köhler, are truly electric boat pioneers who researched the possibilities for non fossil fuel boats starting in 2004 and sailed for 5 years and 15,000 NM before building the world’s first fully self-sufficient and purely solar powered bluewater catamaran, Solarwave 46, in 2009. By 2018 their solar-powered SILENT 64 crossed the Atlantic Ocean on the power of the sun and Silent-Yachts now has a full range of zero emission ocean going cats.

The Silent 60 is the most popular model, and not just with Gussies voters. The company added a second production line in early 2021 to meet demand and now has the capacity to build 15 Silent 60s a year.

Category Finalists: Greenline OC 68 • Helgeland-Plast Elida • Northman Nexus Revo 870 • SunConcept CAT 12.0 Cruise • Vita Lion

Excellence in Electric Boats Over 8 metres / 26 feet: In Development
Aquon One
Swiss Sustainable Yachts

The Aquon One is the first Gustave Trouvé winner to incorporate hydrogen into its energy storage and propulsion system. Using electricity from the rooftop solar panels to produce hydrogen from desalinated sea water, the gas is compressed for storage, enabling the twin 100kW electric motors and living quarters of the 19.5m / 68ft catamaran to be powered by fuel cell and/or lithium-ion battery. The Aquon website has typical usage examples.

An intelligent energy management system monitors everything, including the smart home technologies and IoT-enabled devices throughout the 250 sqm (2,700 sq ft) of living space.

Category Finalists: Silent Straits Sialia 57 • 80 SunReef Power Eco

Excellence in Electric Boats Designed for Paying Passengers: In Production
The Maid of the Mist

There may be no better testament to the capabilities and reliability of electric propulsion than the new (launched October 2020) Maid of the Mist ferries which can carry up to 600 people right up to, and then pull away from, Niagara Falls and the suction power created by 600,000 gallons (2.25M litres) of water falling each second.

The twin motors can reach an output of 400kW, with an ABB Power and Energy Management System providing 316 kWh total storage capacity and the batteries being recharged after each trip with clean electricity generated by…Niagara Falls!

Category Finalists: Ampereship Solar Ferry ASF 25 • EA Mine Smart Ferry • Hunter’s Yard, UK • Soel Yachts SoelCat 12 • TRITON DeepView 24
