We design and build hydrofoil vessels at EPFL Innovation Park in Lausanne.
Two vessels in development, one engineering standard across both.
Short-range water transport is stuck in the past.
Ferries, shuttles and private vessels on lakes, rivers and coastal routes still rely on combustion engines. The environmental, economic and regulatory costs of that choice are rising every year.
Inland and short-sea vessels operate close to population centres. Every journey releases CO₂, NOx and particulates – exactly where they harm air quality and public health.
Diesel prices, maintenance complexity and carbon taxation keep pushing up the cost of combustion vessels, while clean alternatives drop in total cost of ownership.
IMO targets, local bans on combustion on inland waterways, and low-emission harbour zones make it harder every year to plan a diesel fleet that will still be operating in 2030.
Hydrofoils + clean propulsion =
a viable path to zero-emission maritime.
By lifting the vessel above the water, hydrofoils eliminate most of the hydrodynamic drag. That is how electric and hydrogen propulsion become practical at the speeds and ranges short-range passenger transport actually requires.
A physics advantage, applied with precision.
Our vessels use active hydrofoils, carbon-fibre wings submerged below the hull, that lift the boat above the water surface once in motion. The result: less drag, zero wake, the silence and comfort that aviation-grade foiling allows.
Paired with electric or hydrogen propulsion, this makes zero-emission operation an economic decision, not a compromise.
Up to 85% less energy per kilometre
Drag reduction through active foiling
Zero direct emissions
Battery-electric or hydrogen fuel cell propulsion
Zero wake, minimal noise
Low impact on shorelines, ecosystems and coastal communities
Lower cost of ownership
Less fuel, less maintenance, less downtime
Four rules we work by.
Not slogans – the working principles that guide every technical and business decision we make.
Two vessels. One standard.
Precursor and PAX 100 form our current product line. Both are built to a single engineering standard – the discipline that protects our ability to deliver.
Traceable by design.
Every figure we publish will be the result of work we can explain, challenge and reproduce. What we’re still developing stays inside the company until it meets that bar.
Zero-emission as the starting point.
Not a feature we added. The starting point from which every other design decision is made.
A path, not a forecast.
Milestones we commit to, not calendar years we cannot fully control. Progress that is earned, not announced.
Our roadmap is defined by product milestones – not by fixed calendar years we cannot fully control. Each phase advances when the engineering, customer commitment and industrial readiness align.
Engineering validation, supplier integration, and pre-commercialisation with early pioneers customers.
First Precursor units delivered. Parallel design and prototype work on the PAX 100 ferry platform.
Whether you’re an operator planning a fleet transition, a private buyer exploring a zero-emission vessel, or an investor looking at maritime decarbonisation with realism –
we’d be glad to have the conversation
