| IN A NUTSHELL |

The world of yachting is increasingly aligning itself with sustainable technologies, and the recent launch of the Sunpower Solar-eJET 3.3m marks a significant step in this direction. This inflatable tender, engineered by Sunpower Yachts International, is designed to recharge directly from a yacht’s integrated solar energy system. This innovation aims to extend the energy independence of solar-equipped yachts to their auxiliary craft, eliminating the need for conventional refueling or reliance on shore-based electrical grids. As more yacht owners seek environmentally friendly solutions, the Solar-eJET offers a glimpse into the future of clean marine innovation.
Providing a Consistent Energy Ecosystem
The Solar-eJET is not just a standalone innovation; it is designed to integrate seamlessly with the entire Sunpower fleet, including the company’s larger solar-electric yachts. This integration creates a consistent energy ecosystem from the main vessel to the tender. At the core of this functionality is a direct charging interface with the mothership. The tender can be stowed in a purpose-built bay on the yacht, where a built-in connection point allows it to be plugged into the solar charging port.
“This intelligent interface ensures the tender’s battery is continuously topped up from the yacht’s solar array, so it is always ready for use the moment it is deployed,” explained the company in a press release.

This feature eliminates the need for trailing fuel cans or relying on marina power, making the tender as self-sufficient as the yacht itself, always powered by the sun and ready to go.
High-Performance with Raw Power
The propulsion system of the Solar-eJET is a testament to its high-performance capabilities. It is equipped with a 10 kWh lithium battery pack that powers a 22 kW electric motor, which the company rates as equivalent to a 30 horsepower conventional engine. The advanced jet drive, powered by a high-performance brushless DC motor, is liquid-cooled to ensure consistent performance under load.
This electric propulsion system is not only powerful but also environmentally friendly. It operates without direct emissions and with significantly reduced noise compared to internal combustion engines. Additionally, the jet drive enhances safety for swimmers and allows for operation in shallow waters, where an exposed propeller would pose a risk. The tender is specifically designed for inshore coastal use under Design Category C, ensuring it meets stringent safety and performance standards.
Use of Marine-Grade Aluminium
The construction of the Solar-eJET emphasizes durability and resistance to harsh marine environments. Its hull features a deep “V” design made from marine-grade aluminium, chosen for its strong resistance to corrosion in saltwater settings. This design choice ensures that the tender can withstand the challenges of oceanic conditions while maintaining structural integrity.
With a dry weight of 231 pounds (excluding the battery) and a maximum load capacity of 930 pounds, the tender can comfortably seat up to five passengers. Standard equipment includes a welded aluminium deck with a grey and black foam teak surface, integrated cushioned seating, a mechanical steering system, waterproof LED navigation lights, an anchor box, grab rails, and a bow locker. These features highlight the tender’s practical design for everyday use and its adaptability to a variety of maritime activities.

As the yachting industry continues to evolve, the introduction of the Solar-eJET 3.3m represents a significant leap forward in integrating sustainable practices into marine life. By eliminating the need for traditional fuel and reducing dependency on shore-based power sources, it sets a new standard for eco-friendly boating. As more innovations like this emerge, one must wonder: how will these advancements redefine the future of the marine industry, and what further technological breakthroughs can we expect in the coming years?
Wow, this sounds like a game-changer for the yachting world! 🚤🌞
Is the solar charging system effective even on cloudy days?
How long does it take to fully charge the battery from the yacht’s solar panels?
Love the idea of a whisper-quiet engine. No more noisy excursions! 🎶
This seems like a great step towards sustainable boating. Thanks for sharing! 😊
Isn’t the 22 kW motor a bit underpowered for some conditions?
Will the Solar-eJET work in colder climates where sunlight is limited?
The deep “V” hull sounds robust. How does it handle rough seas?
