CMC Marine Expands Electric Stabilisation and Thruster Range for Larger Yachts

CMC Marine is bringing a wider package of new stabilisation and manoeuvring hardware to Monaco Yacht Show 2026, including Low Aspect Ratio stabiliser fins, new Waveless STAB 50 and STAB 60 units and five-blade propellers for its Dualis Electra thrusters. The products sit alongside the company's Energy Recovery System, which Superyacht Guide covered separately earlier this month.

The new hardware focuses on reducing hydrodynamic drag, smoothing thruster output and expanding electric stabilisation into larger yacht applications. CMC Marine is also showing a redesigned touchscreen interface with CAN NMEA 2000 connectivity for integration with the yacht's onboard network.

LA fins target up to 30 percent lower drag

The new Low Aspect Ratio fins were developed by CMC Marine's in-house research and development team for Stabilis Electra systems. The company says a lower aspect ratio and rounded leading edge reduce turbulence and can cut hydrodynamic resistance by up to 30 percent compared with the reference configuration.

The range is available for fin areas from 2.10 to 7 square metres. Lower drag can reduce the energy penalty associated with carrying stabiliser fins through the water, although the actual effect on a yacht's fuel consumption will depend on hull form, speed and operating profile.

Waveless STAB 50 and 60 move into larger yachts

CMC Marine has added the Waveless STAB 50 and STAB 60 to its compact electric stabiliser range. The company says the two units extend Waveless applications to yachts up to around 45 metres and displacement above 200 tonnes while keeping machinery-space requirements comparatively small.

Compact installation volume can be particularly important during refits, where stabilisation equipment must fit around an existing machinery layout. It can also give naval architects greater flexibility on new builds where technical-space allocation competes directly with guest accommodation and storage.

Five-blade thruster propellers smooth thrust delivery

Dualis Electra thrusters are also receiving a new five-blade propeller geometry developed by CMC Marine. The company says the design can reduce thrust fluctuations by up to 30 percent, with the aim of improving manoeuvring precision while lowering noise and vibration transmitted through the yacht.

Thruster comfort is most noticeable during close-quarters manoeuvring, when repeated power changes can generate strong acoustic and structural feedback on board. Smoother thrust delivery therefore has implications for both control response and guest comfort in harbour.

New touchscreen connects through NMEA 2000

The product update is completed by a capacitive touchscreen with revised graphics and improved readability in direct sunlight. CAN NMEA 2000 ports allow the display to exchange information with the wider onboard network, including propulsion signals and GPS data.

Taken together, the Monaco package shows CMC Marine developing the stabiliser, thruster and control interface as a connected system rather than as separate pieces of hardware. That direction is increasingly relevant on electric and hybrid yachts, where energy use, control software and machinery integration need to be considered together from the design stage.
