CONSULTANCY

CJR’s expertise and attention to detail from the design to manufacturing to after-sales support, together with our progressive approach to the industry has allowed us to offer a number of services to boat designers, builders and operators.

At the design phase, we offer a boat performance and propulsion analysis, including CFD predictions, FEM analysis, propeller and sterngear design, shaft alignment and lateral vibration analysis calculations.
We also offer a trial service using TrialsAPP – developed by CJR exclusively for accurate sea trials data acquisition. TrialsAPP links closely with our problem solving service to analysis and identify sources of excessive vibration on a boat as well as boats that are underperforming.
