CJR Propulsion can now design and supply larger propellers, like this pair of 1.8m 5-blade propellers, which are leaving the factory this week and are destined for a 55m superyacht currently undergoing a refit.
Using the latest CFD tools, our experienced team will identify the optimum bespoke propeller design for your vessel and needs. Our propellers are proven to:
– increase top speed
– increase range and reduce fuel consumption
– last longer
– reduce noise, vibration and cavitation.
We can also analyse the entire propulsion system of your boat starting from hull resistance prediction and hull propulsive factors. We select the most efficient gear ratio, recommend changes if needed and analyse flow in every point under the hull using the most advanced CFD tools developed specifically for our requirements.
This development means we can now supply to larger vessels, including fast ferries, superyachts, and larger commercial vessels. To find out more, please get in touch: [email protected] call +44 (0)23 8022 2032 or take a look at our website.
Our custom propeller range:
NAUTICA
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.
MRK REVOLUTION
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.
Billfish Propeller
Our Billfish propeller range is designed specifically for high speed Sportfish boats and has proven to outperform competitors at speeds of up to 45kts. The design and manufacture of the Billfish propeller takes into account the specific operating requirements of the Sportfish market, including maximum speed but also the ability for operators to ‘backdown’ on fish. We have even had reports that the CJR Billfish acts to ‘bring up the fish’.
MRK SUPERPROP
The MRK Superprop range has been developed specifically for high speed vessels (sport boats of 32 knots plus, production yachts and patrol craft) and provides the ultimate in performance at sea. After the propellers are tailored to the particular vessel’s specification, the unique profiles are then optimised to deliver maximum speed, responsiveness and efficiency.
MRK PILOT
The MRK Pilot is designed specifically for workboats, in particular, pilot boats. These propellers 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.
