Electric propulsion systems manufacturer ePropulsion has entered into a new collaboration with Guangdong, China-based Heysea Yachts to introduce a new fully electric catamaran at last week’s International Multihull Show in La Grande Motte, France, where it made its international debut.

The all-new Seaview 59 builds on the success of the firms’ previous collaboration, the Seaview 50, which was launched in 2024, representing a milestone in the commercial application of new energy solutions in the yachting industry, according to the firms.

The Seaview 59 is powered by an advanced ePropulsion photovoltaic energy storage system with five battery packs, a high-voltage distribution box, two solar inverters, and approximately 1,900W of solar panels. Additionally, the system can be customised based on personal needs, offering flexible options for battery capacity, MPPT controllers and daily inverter power.

The yacht’s hardtop-mounted solar panels harness sunlight to generate clean energy, which is then stored in a 58kWh lithium iron phosphate battery. While solar energy can be used as the primary power source, a generator or shore-based charging station can also be used to ensure continuous power availability.

Once fully charged, the system seamlessly powers essential onboard functions such as air conditioning for up to eight continuous hours, providing a quiet and comfortable overnight stay without relying on a generator.

“The Seaview 59 represents a major step forward in sustainable yachting, combining innovative energy solutions with world-class design,” said ePropulsion CEO, Danny Tao. “Our continued partnership with Heysea Yachts showcases the limitless potential of clean energy in the marine sector. We are proud to debut this vessel at the International Multihull Show, bringing a new era of electric-powered sailing to the global stage.”

Following its public exhibition, the Seaview 59 will be officially delivered to its new owner who plans to embark on a voyage through the Mediterranean, showcasing the yacht’s capabilities in real-world sailing conditions.

“We are committed to pushing the boundaries of yacht design and technology,” said Heysea Yachts founder and chair, Allen Leng. “The Seaview 59 is a reflection of that vision; a vessel that merges performance, comfort and sustainability. Partnering with ePropulsion allows us to deliver a smarter, cleaner sailing experience that aligns with the future of the marine industry.”
