Boatbuilders and designers are constantly searching for new ways to improve performance and efficiency. As a result, increased emphasis is being placed on advanced propeller design, meaning that standard or off the shelf designs may no longer provide an acceptable solution.

A highly advanced and unique software programme was developed exclusively for CJR to aid the development of the new propellers. Using lifting surface theory, integrated with computational fluid dynamics, CJR has been able to test the new propeller designs and predict a vessel’s performance in realistic conditions with an extremely high degree of accuracy.

A number of the M-R-K Superprop designs have now been installed and trialled with outstanding results. In each individual test, the performance of the vessel fitted with the M-R-K Superprop has been dramatically transformed by achieving higher top speeds, greater responsiveness and a smoother and quieter operation. In addition, the vessel’s fuel efficiency and range has significantly increased. The most impressive aspect of these trials has been the accurate correlation between CJR’s predicted data and the actual test data.
