The Surface Drive System SDS has been specifically designed to deliver exceptional performance to fast planing yachts, sport fishing boats, racing boats and professional applications where acceleration, high speed and endurance are a necessity such as ambulance, pilot boat, patrol boat, high-speed interceptor, RIB, search and rescue vessel, coast guard…

A complete propulsion package including :

  • A pair of SDS surface drives trimmable and steerable
  • A pair of surface piercing propellersin NiBrAl (Class S) machined with CNC milling machine
  • Integrated panel
  • Hydraulics and steering equipment
  • Emergency backup system
  • Cardan shafts
  • Indicators and sensors
  • Coupling flanges
  • Designed and manufactured in our workshops in France

If your vessel requires more than a pair of drives, or options such as autotrim, giroscope, motor load management, pre-programmed position, connection to a main control panel please contact us our R&D will be pleased to study your specifications and offer a customized package.

Reliability & Efficiency

With our SURFACE DRIVE SYSTEM, all vital components are protected from salt and water corrosion as all cables, sensors, hydraulics, hoses, and electric connections are inside the engine room.
Every part of the SDS is thought and conceived to be heavy duty and has a rigourous quality control at each production step.

High strength material such as NiBrAl is used for boat propulsion endurance and performance. Please consult our manufacturing processes.

R&D

Years of research, development and rigourous testing have resulted in the development of SDS, the most reliable surface drive transmission system.

The constant effort in R&D by FRANCE HELICES has improved the efficiency of the surface piercing propellers up to 10% during the last decade. The FH5SSP model shows an efficiency above 75% in the cavitation tunnel test.

Surface piercing propeller design reduces underwater drag 50% at full speed, over conventional propellers while delivering excellent fuel efficiency and comfort.

FRANCE HELICES Surface Piercing propllers are manufactured to perfection on the latest 5 axis CNC machine according to ISO 484/2:2015 with a high degree of precision of class S tolerances. These high quality propellers made in NiBrAl are ideal for planing yacht, coast guards, high speed commercial vessel, navy.

Vessels requirements to implement an SDS

THE HULL

The hull form must be a planing hull type.

THE ENGINE

SDS are appropriate to diesel engines, gasoline engines, hybrid engines, electric and turbines engines.

POWER/WEIGHT RATIO

To improve speed, compared to conventional propulsion, the target must be above 25 knots and power/weight ratio must be above 50 horse power per tons.

Easy installation & maintenance

Your shipyard technicians will assemble the SDS to the vessel. A hull perforation drawing along with an installation instructions manual will be supplied. An annual maintenance is recommended for the best performances.

Certification

Our propulsion systems can be certified by the main classification societies : BV, Lloyd’s, RINA, ABS, CCS…

Environment

Fuel efficiency with an SDS propulsion: 15% saving compared to conventional propulsion.

Since 2014, our company has been committed to CSR 26000 and Innovation.
Social, economic and environmental responsibility is part of our company’s internal strategy.
Our teams are aware of and committed to an environmental approach aimed at reducing its environmental impacts and preserving the environment.

Old propellers and SDS bodies are recyclable. Please insure them a second life. Metal recycling protects the environment and saves energy.

Several tons of metals are collected and sorted each year and sorted each year from our factories by recognized independent organizations.
