Island Engineering, formed in 1999, is dedicated to design and engineering support of high performance marine vehicles- primarily for the development of advanced ride control systems. These systems are analogous to an aircraft flight control system. Unlike traditional fin roll stabilization systems, a ride control system often reduces dynamic variations in pitch, roll, yaw and/or heave motions simultaneously- while concurrently maintaining list, trim, heading or height above the surface at user-defined values.  Proper design and implementation of the entire integrated system, from the effectors and their servo dynamics to the main control algorithm software, is essential in achieving the highest possible performance.

Island Engineering personnel employ 3D CAD/CAM, Algor FEMPRO FEA with MES, plus various vortex lattice and panel based CFD analysis tools to optimize the effectors for these systems. Sea-keeping simulations, model tests, a vast experience base and scientifically performed sea trials are also used to refine system parameters.

The most advanced IEI motion stabilization system, fielded jointly with Quantum Marine Engineering of Florida, is currently installed on the U.S. Navy’s LSC(X) ‘Sea Fighter’. The system consists of two actively controlled titanium ‘T’ foils mounted near the bow, two active transom interceptors, and two actively controlled flapped skegs for yaw control. System components are linked via an EMI resistant fiber optic LAN. 

‘Spectrum’ systems can be provided for vessels of all types in the 50-300’ range. IEI recently installed yacht trim tab systems on a 56 Ft monohull, as well as a 65 Ft catamaran built by Multihull Technologies in Florida.

Maritime Applied Physics Corporation (MAPC) provides a mix of scientists, engineers, naval architects and technicians who are motivated to move ideas from concept through design and prototype. This work is performed for U. S. Government sponsors as well as commercial organizations. In most instances, MAPC works in the pre-competitive stage of development where the sponsor can use MAPC design materials and prototype hardware to obtain low cost production at low risk. MAPC maintains staff and facilities to prototype complex mechanical, electrical, thermal and electronic systems.

NAIAD DYNAMICS® combines Stabilizer and Ride Control System manufacturers Naiad Marine Systems®, Maritime Dynamics, Vosper Motion Control®, Vosper Stabilizers, VT Marine Products and KoopNautic Holland.  The full integration of these jointly-owned businesses occurred in early 2009 when NAIAD MARITIME GROUP, INC acquired all global operations and reorganized them as NAIAD DYNAMICS with interlinked facilities across the USA, in the UK and Netherlands.


Responsible for more than 10,000 stabilization systems in the luxury yacht, commercial ship and military ship markets—including 50 of the world’s Navies, most of the world’s fast ferries,  and more luxury yachts than any other company. The combined fielded experience and technical expertise of NAIAD DYNAMICS is unmatched in marine motion control.


Proven applications include displacement and planning monohulls, catamarans, trimarans, surface effect ships (SES), SWATH, SLICE, RHIBS and other advanced hull forms from 10 to 150m.  Recent military applications include the US Navy’s sophisticated 115m Freedom Class Littoral Combat Ships and Royal Norwegian Navy Skjold class SES.


Extensive FEA engineering design, CFD hydrodynamic  design, naval architecture  and structural analysis, highly correlated proprietary ship modeling and simulation, full CNC manufacturing to US military aerospace standards, fabrication, full scale assembly and testing, tear down and repair facilities,  dynamometer load testing, motion simulation hydraulic testing, electrical assembly and  testing laboratory, extensive software engineering and programming.
