Our story


Wavefoil has developed retractable bow foils that provide significant fuel savings, reduced motions and a more comfortable experience at sea.​

Combining a smart retraction mechanism with the use of light but strong composite materials, Wavefoil is bringing wave propulsion to the market.



Exploiting the potential of wave energy

It has been known for over 150 years that vessels with wings – or foils – in the bow can be partly or solely propelled by wave energy. The foils generate lift when the vessel is moving up and down in waves, and the lift typically has a forward thrust component larger than the drag.

Put simply, wave power is directly converted into propulsive power.

A vessel in waves experiences additional resistance compared to calm-water operation. For wave lengths similar to the hull length, this additional resistance will be amplified due to resonance, implying large heave and pitch motions. Wavefoil’s retractable bow foils dampen these motions so that the additional resistance decreases.

So how much fuel can you save? That depends on the ship, its speed, the foil size and location and the wave conditions. For a 100 m long ship operating in a wave-rich area, with constant brake power equivalent to a calm-water speed of 14 knots, research shows that an average fuel saving on the order of 20% can be achieved. Lower brake power gives higher percentage fuel saving.

Fuel savings are not the only benefit of bow foils. Increased comfort, reduced vibrations, less spray, increased operability and the ability to maintain higher speeds in waves for a given power are some other perspectives.

Eirik holds a Master's degree and a PhD degree in Marine Technology from the Norwegian University of Science and Technology (NTNU). His PhD thesis, titled Wave Propulsion of Ships, studies the effect of bow foils by means of simulations and towing tank tests. After obtaining his PhD, Eirik continued to explore the benefits of bow foils as a Postdoctoral Researcher at NTNU.


Sven holds a Master's degree in Industrial Economics and Technology Management from NTNU and has diverse experience within both early stage technology companies and politics. He is co-founder of OptoScale, which develops a tool for precise bioscale measurements. Sven is a partner in CoFounder and has been engaged as Wavefoil's CFO, where he is responsible for the economy and business development.


Audun submitted his Master's thesis in Marine Technology at NTNU in 2017 and subsequently started working as CTO of Wavefoil AS. He is the inventor of Wavefoil's retractable foil mechanism and has been involved in developing retractable bow foils since the fall of 2015. Audun is responsible for the technical development in Wavefoil.
