Quantum e-FIN™: Fully Electric Stabilization with Up to 80% Lower Power Consumption

Introduced two years ago, Quantum Marine Stabilizers’ fully electric e-FIN™ is now operating successfully on several yachts following refit installations. From using up to 80% less power underway to almost doubling service intervals from 8,000 to 15,000 hours, the Quantum e-FIN™ brings a different approach to yacht stabilization. Designed for yachts, commercial and military vessels in the 40–80 meter range, the system offers an efficient alternative to conventional hydraulic stabilization.

Reduced Power Consumption

Power consumption is one of the e-FIN’s most notable advantages. Measurements from a real-world case study show that the system consumes 60% less power than a conventional hydraulic system at zero speed and up to 80% less underway. Idle power consumption is also reduced significantly, from approximately 20 kW to just 1 kW.

These savings are supported by Quantum’s specially developed control algorithm, which enables energy recovery and storage through an integrated energy storage system. While underway, energy recovered through fin movement can be stored and reused when additional power is required, further improving overall efficiency.

Longer Maintenance Intervals

The e-FIN extends service intervals from 8,000 to 15,000 hours, almost doubling the operating time between services. With fewer components and a compact design, installation and servicing are also simplified, potentially reducing maintenance costs and downtime.

Based on projected fuel and maintenance savings, Quantum estimates a return on investment of approximately three years, depending on vessel operation.

Quieter Operation and Smaller Footprint

Noise levels are reduced to 62 dB, compared with 75 dB for a standard hydraulic system. This 13 dB reduction represents a noticeable improvement in onboard comfort, as a 10 dB difference is being perceived as approximately half as loud by the human ear.

The system also eliminates the need for a dedicated cooling-water system and requires more than 35% less installation space, particularly beneficial for refit projects where space is limited.

Performance and Installation Options

Beyond efficiency, Quantum reports improvements of up to 30% in fin range, rotational speed and torque performance. The e-FIN can be installed on a newbuild or retrofitted to an existing vessel, including conversions from existing Quantum XT™ stabilization systems.

With several successful refit installations already in operation, the e-FIN demonstrates the potential of fully electric stabilization. Combining reduced energy consumption, longer service intervals and a smaller footprint, it offers practical operational advantages for yacht owners, operators and yacht management companies.
