What is the Wiocor Energy DIY Electric Sailboat Project?
The Wiocor Energy project is an exciting DIY initiative focused on converting a standard 38–40 ft sailboat from diesel to full electric propulsion. It’s designed for those who dream of living aboard their sailboats and embarking on long voyages with complete energy independence. The goal? To achieve total autonomy using cutting-edge technologies that are becoming more accessible and affordable every year. This project isn’t just about swapping engines; it’s about rethinking how a yacht generates and stores energy — integrating solar cells, energy storage systems, and a high-power electric drive to create a quiet, efficient, and eco-friendly sailing experience. It’s a pilot project aiming to pave the way for families to live and travel sustainably on the water, with minimal costs and maximum freedom.
Main Benefits of the Wiocor Energy Project
Here’s what makes this project stand out:
- Safe 48V system voltage — no high-voltage hazards, easy to maintain
- Lightweight electric drive system weighing just 50 kg, delivering 30–50 kW of thrust
- Integrated solar cells smartly embedded into hull, boom, deck, mast, and cabin roof
- Modular Marine Rack System (MRS) lithium-ion batteries with up to 4,000 full cycles
- 30% higher energy density and 230% longer life cycle compared to competitors
- Silent, vibration-free propulsion with minimal onboard noise
- Hybrid options possible — combining sails with electric power for ultimate autonomy
Off-Grid Sailing at Safe Voltages of 48 Volts
One of the coolest things about this project is the focus on safety and simplicity. Operating at 48 volts means no need for complicated high-voltage safety measures, making installation and maintenance a breeze. This low-voltage system reduces weight and energy consumption, while still delivering powerful thrust. Plus, it’s vibration-free and super quiet — a huge upgrade from noisy diesel engines. The compact design also frees up precious space on board, which is always a win for sailors.
Integrated Solar Cells and Energy Storage Systems
Wiocor Energy takes a smart approach to solar power by integrating ultra-thin, robust solar cells directly into the boat’s surfaces — think hull sides, boom, deck, mast, and even the cabin roof. This clever use of space maximizes solar energy generation without compromising the boat’s aesthetics or performance. On the energy storage side, the project uses a modular lithium-ion battery system (Marine Rack System) built with high-energy graphite/nickel-manganese cobalt lithium oxide cells. These batteries are designed for deep discharge and long life, allowing sailors to extend their trips without worrying about running out of power.
High-Power Electric Drive and Hydro Generation
The heart of the conversion is a high-efficiency electric saildrive or shaft system with an integrated controller. This system not only propels the yacht but can also generate power hydro-electrically while sailing, charging the batteries on the go. It’s a win-win — propulsion and power generation combined in one sleek package. The 48V technology keeps things safe and simple, while the system’s lightweight and compact design means less energy consumption and more room on board. Maintenance? Minimal. Noise? Almost none. It’s a game-changer for anyone wanting to sail off-grid without the usual diesel engine headaches.
Project Impact on Sustainable Development Goals (SDGs)
- SDG 7: Affordable and Clean Energy — promoting renewable energy use on boats
- SDG 9: Industry, Innovation, and Infrastructure — advancing marine electrification technology
- SDG 11: Sustainable Cities and Communities — supporting sustainable living on the water
- SDG 12: Responsible Consumption and Production — encouraging eco-friendly boating practices
- SDG 13: Climate Action — reducing carbon emissions from maritime transport
- SDG 14: Life Below Water — minimizing pollution and protecting marine ecosystems
Looking Ahead: The Future of DIY Electric Sailboats
The Wiocor Energy project is more than just a single conversion — it’s a stepping stone toward a broader movement of sustainable sailing. The practical experience gained here will help develop full conversion services and provide a solid theoretical and hands-on foundation for others eager to electrify their boats. With the rise of affordable, efficient components and smarter energy solutions, the dream of living off-grid on a sailboat, powered by clean energy, is becoming a reality for many. It’s about freedom, innovation, and respect for the environment — all sailing together into a cleaner future.
