Hand-Built Solar Yacht Completes 3,100-Mile No-Fuel Voyage
Lukas Sjoman spent 200 days building Helios 11, a solar-powered yacht that sails entirely on sunlight. He recently completed a 3,106-mile journey from Finland to Ibiza without using any fuel. Along the way, their utility dinghy was stolen at a Spanish anchorage, so the crew built an emergency catamaran tender from foam and wood to ferry supplies ashore. They also faced vandal attacks when rocks thrown from a nearby bridge struck the solar panels. Despite these setbacks, Helios 11 maintained consistent power output throughout the trip. Sjoman’s monitoring confirmed stable solar input before he finally reached Ibiza’s sunny shores — a milestone for sustainable marine travel.
