While the world marvels at gigantic superyachts that are more about lifestyle and lavish interiors than the sea and the sailing experience, there is a Finnish engineer who is doing it right at a fraction of the cost. No shipyard, no nautical design teams, no interior stylist. Lukas is managing the entire show single-handedly, and he has a boat to prove it. Meet the 35-foot Helios 11, a hand-built prototype assembled in roughly six months using off-the-shelf panels and lightweight materials. He calls himself the Solar Man who works, lives, and thrives on his solar yacht. His proudest achievement is that Helios 11 “uses less electricity than a household blender” while cruising.
With a 6 kW solar array, the boat achieves speeds of around 7 knots in good sunlight, with peaks of nearly 8.5 knots, supported by simple sails for stability and auxiliary propulsion. One video at a time, he is showing the world it is possible to live aboard a yacht without shore power, marinas, or fuel stops. Leading by example, he demonstrates an autonomous setup with always-on connectivity and essentials stacked for weeks and months of consumption. This man is not trying to impress the dock; he is trying to liberate himself from it. There is literally no need or desire to leave the floating home that is Helios 11. Let us take a look at his journey below, already sounding incredible, and deserving a bird’s-eye view of his sheer genius.
Building a boat is no small undertaking, even without any frills. A 35-footer does not fit in any backyard, which is why Lukas built a shed on an abandoned property to construct his 35-footer.
No funding, no professionals, no laborers. The enthusiastic and determined Finnish engineer managed the entire build on his own from start to finish and, as he said, “with a lot of stubbornness.”
Lukas used basic solar panels just like the ones seen on houses. From the roof to the sides, everything is sheathed in energy-generating panels.
The boat is a simple yet functional prototype. Even the steering wheel is made of plywood, but it works well enough to leave Finland and explore the waters.
Helios 11 has no petrol engine onboard. It runs solely on solar energy, with background support from simple sails. Under sunny conditions, the boat cruises at about 7 knots, with power consumption comparable to a household blender.
There is no fancy interior, no marble en-suites, and no heavy furniture. Basic woodwork keeps the boat lightweight. It is essentially a prototype that Lukas is currently taking on sea trials.
Before Helios 11, the engineer crafted a smaller boat and lived aboard it. He called that period “embracing sea sovereignty.” The planning for the 35-foot boat took shape here and prepared him for what came next.
The next boat is already in the planning stage. Christened Helios 15, it will be a 49-foot, 2 to 2.5-ton, ultra-lightweight solar-powered boat targeting an impressive 10-knot speed. Helios 15 will feature more expensive materials, better finishes, and perhaps even a sauna to relax and unwind on an unending journey.
And if Helios 11 is proof of concept, Helios 15 could become something the superyacht world cannot ignore, a truly self-sufficient luxury boat that does not need the world; it can outrun it.
