As awareness of the benefits of its unique design and manufacturing capability proliferates through the marine industry, an increasing number of boatbuilders, refit yards and owners are looking to CJR to help solve complex propulsion-related challenges or commission performance-oriented, highly-efficient propulsion packages.
In the last year, 50 vessels commissioned bespoke flow-aligned rudders, which reduce drag and improve efficiency through a twisted profile that’s aligned with a propeller’s flow angles along its entire span. Equally, over 500 projects have benefited from CJR’s computational fluid dynamics and lifting surface theory, to capabilities to design and build optimised propellers and propulsion packages that maximise performance, efficiency and longevity.
“To be blunt, better is better and quality always shines through. We can demonstrate that we have the capability to produce better quality products than most propulsion specialists, and certainly higher quality and higher performing than any other UK manufacturer. With rising operating costs always on the horizon, customers can’t afford to install inefficient products, and more and more boatbuilders are promoting optimised propulsion systems as a specific customer benefit. Our customer base and the complexity of our output is growing because of these factors, demonstrating that the marine industry is becoming more aware of the available opportunities but also the risks that can be easily avoided,” commented Alex Stevens, Technical Sales Manager for CJR Propulsion and CJR Fabrication.
