Five Hours of Silence: This Battery Integration Is the New Standard for 55-Foot Yachts
The Price of Peace: Addressing Generator Noise
For yacht owners, stabilization at anchor is non-negotiable—but the steady drone of a generator running continuously to feed the stabilizer is often the price of that comfort. This constant background noise ruins serene evenings and peaceful nights at sea. Smartgyro, a global innovator in marine stabilization technology, has responded directly to this real-world operational issue. Their solution, the SG20 gyroscopic stabilizer with battery-powered integration, is debuting at METSTRADE 2025, offering a radical promise: complete stability, total silence.
Innovation Inspired by Owners: The 40–55 ft Segment
The project’s genesis lies in direct feedback from owners of 40–55 ft yachts who wanted generator-free operation. Smaller generators, often operating at high RPMs, are primary sources of unwanted background noise. Smartgyro tackled this by developing a flexible power integration that allows the SG20 to operate seamlessly on battery power for extended periods. Sales Manager Carlo Gazerro noted this was crucial for the segment, delivering “greater freedom, more enjoyable moments on board, and an added benefit for our dealer network”.
Five Hours of Silence: Performance in Night Mode
The core functional benefit is the extended period of generator-free operation. The system, utilizing approved configurations with leading manufacturers like Mastervolt (6 kWh pack), is capable of delivering up to five hours of stabilization in Smartgyro’s night-mode settings. This allows owners to enjoy dinner at anchor or a peaceful night’s sleep without the mechanical intrusion of the generator. The system was rigorously tested on board a Ferretti 52 for two years, confirming that it delivers the same stability and reliability expected from the SG20, now with a new level of peace.
The Smart Integration: Simplifying the Experience
Smartgyro has made integration straightforward and intuitive. The system includes a smart interface that provides a real-time display of battery status and stabilizer performance directly through the Smartgyro UI. This user-friendly feature ensures the captain can manage stabilization and energy consumption seamlessly. This project is a clear example of the ongoing dialogue between Smartgyro’s R&D team and owners/shipyards, ensuring innovations directly translate into enhanced onboard comfort and efficiency.
The Verdict: The Final Word on Comfort
The SG20 with battery integration is a crucial technological leap for the 40–55 ft segment. It confirms that the future of marine stabilization is not just about eliminating roll; it is about eliminating noise. For owners who view their yacht as a true sanctuary, the ability to operate stabilization with unmatched silence and reliability offers a new dimension of comfort. Smartgyro, a part of the YANMAR Marine Recreational Business Unit, continues to pioneer stabilization systems that genuinely respond to real-world needs and redefine the onboard experience.
