No Fuel, No Problem: Finnish Sailor Covers 5,700 km in Custom Solar-Powered Vessel

A Solar Vessel Built from Scratch

According to НВ — Техно: Lukas Schöman, a yachtsman from Finland, has shown that long-distance travel on sunshine alone is possible. He piloted the Helios 11, an 11-meter boat he assembled in a humble shed, from Finland to the Spanish island of Ibiza-about 5,700 kilometers-with stops in Sweden, Denmark, Germany, and France. Throughout the entire trip, the craft never needed a single drop of fuel.

Schöman spent around 200 days building the vessel, which weighs roughly 1.5 tons. Its photovoltaic system delivers about 6 kW of power, working alongside 48-volt batteries, and an auxiliary sail helps save energy when winds are favorable. This kind of long-distance solar voyage offers a rare, real-world test of emissions-free navigation.

Challenges, Grit, and a Stolen Dinghy

The journey was far from smooth. In northern regions, Schöman had to cope with scarce sunlight and unpredictable weather, which put his energy management to the test. During a stop in Spain, thieves took the boat's inflatable tender. Rather than quit, he crafted a replacement from whatever materials he could find-a decision that speaks to both his engineering instincts and his determination.

• Route: Finland – Sweden – Denmark – Germany – France – Ibiza.
• Vessel specs: 11 m long, about 1.5 t, roughly 6 kW output, 48 V battery system.

Schöman's success shines a light on the promise of renewable energy in maritime travel and the value of innovation in tackling environmental challenges. His journey is a practical example of how modern technology can support sustainable tourism and boating. It may also inspire others to explore solar-powered alternatives in the transport sector.
