Naiad Dynamics – The Ship Motion Control Experts™ – is the fusion of legendary stabilizer and ride control system brands Naiad Marine Systems, Maritime Dynamics, Vosper Stabilizers, Vosper Motion Control, VT Marine Products and KoopNautic Holland. Responsible for over 10,000 ship sets of motion control systems in the military ship, commercial ship and luxury yacht markets, including 50 of the world’s Navies, the combined field experience of Naiad Dynamics is unmatched in ship motion control.

We provide innovative turnkey solutions for simultaneously reducing roll, pitch, heave, yaw and sway on a wide range of types and sizes of ships. Our systems are proven in monohulls, catamarans, trimarans, SWATH, SLICE, SES and other advanced hull forms. Let Naiad’s expertise, proven effectiveness and ruggedly designed equipment enhance the performance of your vessel.

Some of the benefits of Naiad Dynamics motion control systems include:

  • Substantially reduce motion sickness, reduce crew fatigue
  • Enhance work effectiveness and safety
  • Reduce cargo and equipment damage
  • Reduce machinery stresses and wear
  • Reduce course corrections and rudder drag due to yaw
  • Continuously optimize trim and heel
  • Minimize motion induced falls and accidents
  • Minimize interruptions of helo and other operations in rough weather
  • Enhance fuel economy/increase speed with same power
  • Maintain speed and course in weather, expand operational envelope
  • Reduce wetted surface and required power

Roll stabilization systems

Naiad Dynamics has supplied more fin stabilizer systems than any other manufacturer. Proven hydrodynamic efficient fins provide dramatic roll reduction underway and while anchored or keeping station. Our stabilization AtRest system was the first successfully installed fin stabilizer that reduced vessel roll at zero forward speed. Naiad/Vosper stabilizers are the equipment of choice, installed in thousands of vessels in demanding commercial and military ship applications.

T-foils provide motion control for a number of hull types. They are available in a number of sizes and configurations, such as retractable.
Active trim tabs provide roll, pitch and trim control.
Active interceptors provide a unique solution for high-speed vessels. They work like the trim tabs, but come in a smaller package.
Fin units are traditionally used on monohulls, but can also be fitted to other hull forms.
Naiad hydraulic power packs supply power for motion control devices and other shipboard equipment.

Ride control systems for ships

Naiad Dynamics pioneered the science of ride control systems (RCS) – simultaneous stabilization of multiple vessel motions while maintaining optimal running trim. Using proprietary motion simulation programs to model a ship’s individual characteristics, Naiad experts analyse data to identify and optimize the best motion control solution, while also providing various alternatives.

Over the last several decades our engineers perfected the development and application of continuously active fins, trim tabs, T-foils, interceptors, lifting foils and air cushion systems – and will select or custom configure a system utilizing any appropriate combination of these control surfaces to suit your vessel objectives.

Advanced digital motion control systems

Our advanced three-term (angle-velocity-acceleration) digital DATUM™ control system represents the culmination of decades of motion control experience combined with cutting-edge technological innovation. Operating on a CANbus network with aerospace-grade sensors, the DATUM is a fully proportional closed-loop system that senses the slightest motion and immediately positions our control devices to arrest wave induced motions before they develop. The ruggedly designed electronic control module is military shock tested, and naval ship approved.

Integrated shipboard hydraulic systems

Naiad Dynamics designs, manufacturers, supplies and supports complete shipboard hydraulic systems. The systems can be powered by engine-driven pumps, or our specially designed hydraulic power packs. Naiad IHS can be designed to accommodate any shipboard hydraulic equipment, in addition to motion control devices. Our hydraulic engineers routinely design systems that power windlasses, winches, cranes, capstans, bay doors, lifts, thrusters and more.

Worldwide support

Naiad Dynamics stands behind every system sold with a superb limited warranty and six sales and service centers, plus a worldwide mobile fleet of authorized dealers. In-stock parts typically ship within 24 hours, and our state-of-the art manufacturing facility ensures quick turnaround on parts throughout the life of the system.
