Naiad Dynamics

Naiad Dynamics pioneered the science of Ride Control over 40 years ago with our revolutionary work with the US Navy and the fast ferry industry. Since then, we have introduced numerous groundbreaking advances in Ride Control System (RCS) devices and controls to keep pace with the expanding diversity of hull forms emerging from the world’s commercial and military shipbuilders. RCS benefits include:

Reduced roll, pitch, yaw, and heave motions.

Reduced motion sickness, crew fatigue, falls/accidents, rough weather interruptions, and cargo/equipment damage.

Automatic motion control and optimized running attitude reduces vessel drag and maintains a straighter course, improving speed and fuel efficiency.

Active T-Foils, Trim Tabs, Interceptors, Lifting Foils, Fins, Rudders and Air Cushions are used alone or fully integrated in combinations to suit ride quality objectives.

Proprietary modeling software developed over decades of experience accurately analyzes a vessel’s motion characteristics, and its effect on seasickness incidence averages. 

Features:

Highest quality materials and workmanship.  Major components machined in-house to US military standards and concurrently produced alongside aerospace machined parts in our ISO 9001:2015 certified facility.

Fully complies with commercial and military design standards.  Proven in demanding high-speed ferry and naval ship applications. 

T-Foil will break away cleanly in the event of a substantial strike to protect hull integrity.  An internal beacon is automatically activated to aid in recovery.

Hydrodynamically-efficient foil section designs available in a variety of standard sizes. 

Naiad’s Interceptor System consists of a pair of transom-mounted blades that are hydraulically or electrically actuated, and controlled by the proven Naiad motion control system. Interceptors generate an increase in pressure on the hull bottom directly ahead of the transom by intercepting the water flow to a greater or lesser degree in continuous proportion to vessel motions.  The resulting forces make it possible to simultaneously damp both roll and pitch motions, and optimize running trim, by automatically varying the deployment of each interceptor in response to vessel motion. 

At speed, the interceptor blades are continuously modulated, extending only a few centimeters below the transom to generate forces on the hull equivalent to the forces produced by a trim tab or fin with much less risk of damage from floating debris or grounding.  Because the system requires very little movement to produce the necessary stabilization forces, the interceptor mechanisms as well as the hydraulic or electric power system are compact and lightweight. This makes installation relatively simple, especially for retrofits onto finished vessels.

Features:

Highest quality materials and workmanship.  Major components machined to US military standards in our ISO 9001:2015 certified facility alongside aerospace machined parts.

Industry first heavy-duty tapered roller bearing construction. Designed for life; no main bearing replacement required.  Compare to wear-prone plain bearings/bushings.

Factory assembled and tested. No disassembly required at installation.

Multiple lower shaft seals encased in an easily accessible housing.

Industry best double spherical Rod End bearings.  Roller bearings (not bushings) at all pivoting locations.

Proven hydrodynamically-efficient foil section designs.

Advanced composite fin construction is galvanically inert and features an encapsulated stainless-steel insert with precision machined self-locking keyless taper.  Steel fins are optional on most models, and standard on Model 925.

Keyless taper allows freedom to install the NAIAD Assembly in any 360° orientation, plus allows the fins to be aligned and realigned in any desired position. Hydraulic taper lock.
