Not all propellers are made equal.
Propeller packages from CJR consistently outperform the competition and are proven to increase top speed, consume less fuel, last longer, and reduce noise, vibration and cavitation.
Every CJR propeller is designed to the highest quality standards and custom-made for the specific vessel in question using advanced design and production technology to do so. Our continuous investment in precision manufacturing technology is combined with a data and intelligence-led mindset, to deliver the ultimate in propulsion performance and efficiency as standard. Equally, every CJR propeller can be manufactured to any classification society rules, including all IACS societies for complete peace of mind.
Our unique end-to-end design and manufacturing process is unrivalled in Europe and leverages the latest in CFD and FEA design software, highly accurate pattern-less moulding, and five-axis CNC-machining to create truly bespoke propulsion solutions that deliver long-term benefits and efficiencies. This means every CJR propeller is designed without constraint, to the precise requirements of the vessel and its intended application.
Customers have reported saving as much as 10% in fuel costs per annum and have increased top speed by up to two knots simply by switching from a set of hand-finished props to a set of fully bespoke CJR fully CNC machined propellers.
The propeller is one of the most sensitive parts of the boat and is impacted by the vessel’s displacement, trim, appendages, hull fouling and engine performance, as well as trial conditions like sea state or wind. Whether your propellers are intended for a superyacht, motor yacht or commercial vessel, you need a propulsion partner that takes the time to understand every relevant factor; how your vessel is being used, its loading and any individual propulsion requirements or challenges. We gather this critical vessel data and use our technology-driven approach, commitment to customer service and manufacturing excellence to provide our customers with the confidence they need – safe in the knowledge that their propeller package will meet their requirements in terms of performance, efficiency, longevity and ride comfort.
Our Nautica propeller range is designed for vessels looking for exceptional performance at lower speeds, making it ideally suited for fishing boats, trawlers, sailing yachts, displacement motor yachts or survey vessels.
Our MRK Revolution propeller range is our most popular custom-made solution, designed for vessels looking for minimal noise and vibration at a medium speed range of 20-30 knots). It is particularly popular with large luxury yachts, semi-displacement and planing production motorboat builders.
The MRK Superprop range has been developed specifically for high speed vessels (32 knots+ sport boats, sports fish boats and patrol craft) and provides the ultimate in performance at sea. After the props are tailored to the particular vessel’s specification, the unique profiles are then optimised to deliver maximum speed, responsiveness and efficiency.
The MRK Pilot is designed specifically for workboats, in particular, pilot boats. These props are designed to withstand the rugged environment that workboats encounter. The propeller profiles are optimised for efficiency and speed while ensuring cavitation erosion is controlled.
CJR has recently launched a rapid turnaround service offering bespoke, fully optimised Class-S propellers in just 14 days or less. Designed for propellers up to 1500mm in diameter, our replacement propeller services can save as much as three months from the typical replacement timeline. For more information, visit our dedicated Rapid Turnaround page.
Replacing a single damaged prop is now significantly easier, quicker and more cost-effective with CJR. Our ability to 3D scan and reverse engineer any propeller to the highest degrees of accuracy is yet another reason to choose CJR. For more information, visit our dedicated 3D scanning page.
