E-MAST: Sustainable energy mast revolutionizing yachting

The modern yachting industry faces a significant challenge: advancing toward self-sufficient, silent, and emission-free navigation. The E-MAST sustainable energy mast for yachts has emerged in response to this need as a new type of sailboat mast capable of generating electric power by harnessing three natural forces — wind, waves, and the motion of the hull.

The system transforms marine-induced oscillations into electricity, even when the vessel is anchored. Unlike traditional systems that rely on solar energy or propulsion-based mechanisms, E-MAST provides a continuous and discreet energy solution that requires no external moving parts.

The mast’s structural design has been meticulously engineered with optimized geometry — thinner at the base, aerodynamic, and equipped with an internal mechanism protected from marine exposure. Its unconventional shape, along with seamless integration into the deck, enables efficient capture of micro-oscillations without compromising the vessel’s balance or visual aesthetics.

E-MAST can be paired with additional renewable energy sources such as solar panels or regenerative propulsion systems, significantly reducing reliance on diesel generators. The result is greater energy autonomy, a reduced environmental footprint, and a quieter, more comfortable onboard experience.

Designed as a structural component of the vessel rather than an add-on, the mast is suitable for both leisure yachts and exploration vessels. Its modular construction allows for scalability depending on a vessel’s onboard energy requirements.

The project is currently in its development and awareness phase. Preliminary estimates indicate that E-MAST could meet a substantial portion of a modern yacht’s auxiliary energy needs, offering an elegant, efficient, and viable step toward zero-emission sailing.

This technology represents a shift in how energy is generated and managed at sea, supporting the broader goal of making sustainability a foundational standard in the future of shipbuilding rather than a selective option.
