Naiad Dynamics began pioneering the science of Ride Control over 40 years ago with our revolutionary work with the US Navy and the fast ferry industry.
An original Naiad Dynamics innovation, Active T-Foils are a reliable and effective ride control device, proven in hundreds of successful installations. Available with active flap, pivoting (with or without active flap) and fully retractable (with or without active flap) in a range of sizes to suit any application. Suitable for monohulls, catamarans and trimarans for primarily pitch and roll control.
Active Trim Tabs are transom mounted flaps that create lift to continuously and automatically control roll and pitch motions while simultaneously optimizing running attitude. Suitable for a wide variety of applications and hull forms.
Like Active Trim Tabs, Active Interceptors are transom mounted and create lift to control roll and pitch motions while simultaneously optimizing running attitude. Instead of a flap, the interceptor deploys a blade that is uniquely strike tolerant, requires less power and space, and simplifies installation.
Our development of Ride Control Systems for Surface Effect Ships (SES) began over 45 years ago with the USN. With precise control of SES air cushion vents and stern seal pressure, Naiad Dynamics Air Cushion Control systems reduce motions and enhance performance.
Naiad Dynamics has supplied more Active Fins than any other brand. Commonly used for roll control underway (AtSpeed®) as well as at anchor (AtRest®), Naiad Dynamics has integrated fins and canards into many ride control applications for roll, pitch and yaw damping.
Active Spanning/Lifting Foils provide motion control and can also provide hydrodynamic lift for multi-hull vessels. The added lift reduces wake and wetted surface for higher speed, and the foils are continuously modulated for motion damping and optimal running attitude.
Naiad Dynamics yaw control fins automatically counteract yaw motions (directional stability) and reduce course corrections and point-to-point times.
Using the ship’s rudders as active motion control devices, the Naiad ride control system integrates with the autopilot control to reduce roll while maintaining course.
The Dynamic BowFoil is an active lifting foil effector that mounts flush with the keel near the bow of the vessel, and uses a flap along the trailing edge of the foil to control pitch and trim. The Dynamic SternFoil mounts on the transom and can have an active flap along the trailing edge, and/or the entire foil can pivot to actively control pitch and trim.
