Introducing EEFS​

The Future of Energy-Efficient Marine Design

 Millions of conventional vessels worldwide still rely on fossil fuels and suffer from high drag, reducing overall efficiency. After years of R&D, we have developed a revolutionary, patented system—EEFS—for V‑bottom hulls, delivering superior performance and energy savings.

At EEFS (Energy Efficient Foil System), we’ve developed a revolutionary, patented solution tailored specifically for V-bottom hulls—a system that significantly reduces drag, improves speed, and lowers fuel consumption.

After years of intensive R&D, our hydrofoil units are now ready to redefine marine performance across both racing and recreational sectors.

Our Core Innovation: A Three-Part System

Front Hydrofoil Unit – Fully Retractable Performance

Our front hydrofoil is fully retractable and engineered with a highly efficient cross-section and optimal aspect ratio. When deployed, it lifts the hull to reduce water contact and dramatically decrease resistance.

Dual Stern Hydrofoils – Smart Mode Switching

At the stern, EEFS features a dual hydrofoil system with two operational modes:

  • Hydrofoil Mode: Foils extend downward to provide lift and stability at high speeds.
  • Trim Tab Mode: When retracted into the hull, they function as traditional trim tabs, ideal for docking or low-speed control

Pitch-Adjustable Propellers – Silent, Efficient Thrust

 EEFS includes adjustable-pitch propellers designed to deliver maximum thrust with minimal vibration, cavitation, or noise. Whether in standard cruise mode or hydrofoil “flight,” propulsion remains smooth and efficient.

Designed for More Than Racing

While our hydrofoils have demonstrated exceptional results in F1 sailboat racing, EEFS is not just for the track. Our system is designed for;

Performance Yachts

Commercial Vessels

Private recreational boats

Eco-conscious marine projects

With its retractable design and wide compatibility, EEFS can be adopted across a broad spectrum of marine applications.

FRONT HYDROFOIL

 The front hydrofoil of the EEFS is fully retractable and engineered with an optimized cross‑section and aspect ratio for maximum efficiency.

PITCH ADJUSTABLE PROPELLERS

 Our adjustable-pitch propellers deliver exceptional thrust with peak efficiency, minimal cavitation, and near-silent, smooth operation—whether cruising or in hydrofoil mode.

DUAL STERN HYDROFOILS

The dual stern hydrofoils operate in two modes. In the deployed position, they function as high‑performance adjustable foils. When retracted into the hull, they serve as conventional trim tabs.

FRONT HYDROFOIL

Front part of the EEFS is completely retractable and designed with an efficient cross section with an optimum aspect ratio.

PITCH ADJUSTABLE PROPELLERS

Adjustable pitch propellers are capable to produce spectacular trust with maximum efficiency, negligible cavitation, no vibration and noise during conventional hull ride or flight conditions.

DUAL STERN HYDROFOILS

There are two mode exist. Mode one is at debased position. In this mode foils present a high performance adjustable hydrofoils. Second mode foils rise to the housing below hull bottom and works as conventional trim tabs.
