a d va n c e d propeller Picture © Sunseeker International Ltd design looks When your customer takes delivery of their yacht they want the ride, power and performance to be as exhilarating and rewarding as they dreamed it would be. CJR have been playing their part in fulfilling this promise for over 50 years. Our dedication to advanced propeller design, craftsmanship and engineering excellence have made us the sterngear suppliers of choice for some of the most prestigious boat builders in the business.

The secret to achieving super smooth power delivery right across the engine rev range is locked in the highly specialised world of fluid dynamics. That’s why our propulsion systems are developed using the latest Computational Fluid Dynamics (CFD) software. fine-tune the design of all the components in a propulsion system, including the propellers, to deliver optimum performance and efficiency – and significant advantages over conventional equipment. Underwater excellence delivers outstanding surface performance • Higher top speed • Better acceleration • Reduced vibration • Improved fuel...

Once you’ ve told us about TONNAGE horsepower & perform ance… Our role at CJR is to work in harmony with yacht designers and builders to achieve the performance and experience that the customer is looking for. & feel With performance at the heart of every one of our propeller and sterngear solutions, we continuously push the boundaries of CFD and Finite Element Analysis (FEA) software. We also develop our own CAD/CAM software and 3D modelling systems to help us achieve maximum efficiency with the least possible weight and drag.

MOULD… Just as with yacht building, successful propeller manufacture depends on the skilful combination of new technologies and experience. We combine three generations of craftsmanship in the fashioning of propellers and sterngear with the science of sophisticated flow-test software to model and control how molten metal will flow and cool in the mould, ensuring that our designs are faithfully replicated in production. M E T A L Developing our own unique metal composite gives us ultimate control of how the finished product behaves. This is just one example of why all aspects of our...

Significant investment throughout our design and manufacturing departments have made our facilities some of the most technically advanced in Europe. This investment enables us to manufacture propellers, prop shafts, P brackets, rudders and sterngear for motor yachts up to 260 feet (80m) in size, quickly, efficiently and to the most exacting tolerances. The partnership of CJR Propulsion and Australia’s premier propeller designer and manufacturer, VEEM, provides clients with the perfect sterngear package for their motoryacht – combining CJR’s leading sterngear systems with VEEM’s superlative...

VEEM SURF ENGINEERING GROUP Improve the performance of a 30m yacht with just 3mm of engineering brilliance The revolutionary Interceptor technology enables all vessels to be launched with the correct propeller every time, by attaining the right engine revs and load without the need to change or modify the propellers. The pitch of the propeller can be fine-tuned to the boat by using different height Interceptor strips on the trailing edges of the blades. Should the pitch of the propeller need to be changed, the old strip is simply pushed out and a new strip of a different height is pushed...

We also manufacture fabricated rudders in a variety of different materials. Manufactured from GRP, Aluminium, Steel or Bronze these are supplied fully machined and, where appropriate, fully assembled. Standard sized items can be supplied from stock. Cast in Aluminium Bronze or High Tensile Bronze which are highly resistant to corrosion, the logs are supplied with water...
