Product catalog summary
Introduction
The NAIAD DYNAMICS Model E-525 Electric Fin Stabilizer is designed for both AtSpeed® and AtRest® stabilization, combining the reliability of ND fin actuator design with an all-electric drive. It features a single AC servo motor-driven linear actuator that provides the torque equivalent to two hydraulic cylinders. Originally developed for naval applications in 2008, it is now adapted for luxury yachts.

Fin Actuator Assembly Features
  • No hydraulics, reducing installation time.
  • Lower profile compared to other electric stabilizers.
  • Available in two motor sizes: 7.5kW and 11kW.
  • Constructed with aerospace-grade materials and workmanship, certified to ISO 9001:2008.
  • Features heavy-duty tapered roller bearing construction, pre-assembled and sealed for easy installation.
  • Greased for life, requiring no annual main bearing maintenance.
  • Double lower shaft seals in a stainless steel housing.
  • Fins can be manually centered and locked.
  • Hydrodynamically-efficient foil section designs with stainless steel Tip Fence.
  • Advanced composite fin construction with a stainless steel insert and keyless taper.
  • Keyless taper allows 360° installation orientation and fin alignment flexibility.
  • Robust construction designed to yield safely to severe impacts.

Application Guidelines
The E-525 model is suitable for yachts with an overall length of 115 to 165 feet and a maximum displacement of approximately 600 short tons. Fin sizes range from 12 to 38 square feet.

Service and Support
Naiad Dynamics offers a limited warranty and global support through sales and service centers, a mobile fleet, and an authorized dealer network. Spare parts are typically in stock and ship within 24 hours.

Digital Control System
  • Features the AVA™ closed-loop control system for maximum roll reduction with minimum drag.
  • Resonant roll reduction typically at 90% with static heel correction and sensitivity adjustment.
  • Enhanced course-keeping and reduced rudder drag improve destination time and fuel efficiency.
  • DATUM™ is the first purely digital fin stabilizer control system operating on a CANbus network.
  • Shock tested and approved for naval ships.

Contact Information
NAIAD DYNAMICS has offices in the USA, UK, and Netherlands, providing contact details for each location.

Conclusion
The NAIAD DYNAMICS Model E-525 offers advanced stabilization technology for luxury yachts, backed by robust support and service infrastructure.

E-525 Electric Fin Stabilizer-1

Introducing the NAIAD DYNAMICS Model E‐525 Electric Fin Stabilizer — combining the proven reliability of the robust ND fin actuator design, with the convenience of all‐electric drive. A single AC servo motor driven linear actuator generates the torque of two hydraulic cylinders. Originally developed in 2008 for Naval applications, now adapted for luxury yachts. With more systems in service than any other brand, ND product innovations are earned from real‐life experience, analysis, and constant development. Install Naiad, Instill Confidence™ Fin Actuator Assembly Features AC Servo Motor Linear Actuator Robust Sealed Feedback Assembly Much lower profile than other electric stabilizer brands. Available in two motor size options: 7.5kW and 11 kW to suit the application. Highest quality materials and workmanship. Aerospace grade machining in‐house to US military standards. ISO 9001:2008 certified facility. Oversized Spherical Roller Bearing Rod End High Grade Cast Housing Industry first heavy‐duty tapered roller bearing construction, fully pre‐assembled and sealed at the Naiad factory for easy installation. Compare to inexpensive and wear‐prone plain bearings/bushings. Greased for life, no annual main bearing maintenance required. Double lower shaft seals encased in an easily accessible precision‐machined stainless steel housing. Fins can be manually centered and locked. Proven hydrodynamically‐efficient foil section designs. Stainless steel Tip Fence (shown), proportionately sized and validated for performance. Advanced composite fin construction is galvanically inert and features an encapsulated stainless steel insert with precision machined self‐locking keyless taper. Steel fins optional. Keyless taper allows freedom to install the NAIAD Assembly in any 360° orientation to simplify installation and maximize accessibility, plus allows the fins to be aligned and realigned in any desired position to suit hull flow lines. Robust fin construction is damage resistant, but designed to yield safely to severe impacts. First choice among discriminating yacht owners and ship builders throughout the world.
