University of Southampton

A session at KTP Showcase

  • Dr Simon Lewis

Project Summary: The initial aim of the KTP was to develop a design tool to enable optimal design for marine vessel-specific propellers and associated stern gear for improved efficiency and reduced vibration and noise. The successfully completed KTP gave the company the capability to produce a bespoke, optimal propeller and associated stern gear package for boats that can be manufactured within a commercially viable cost and timeframe. Optimally matched propellers and associated stern gear will lead to reduced noise, vibration and harshness and increased fuel-efficiency. A greater technical understanding of input flow regime will also significantly reduce the potential for cavitation erosion at high speed, all of which has given the company a unique design capability for this industry segment in Europe. The company believe that this tool has become a unique product with respect to its targeted market (small marine/pleasure craft), and, through effecting a step-change in the process of matching the correct propeller to the specified hull, will enable the company to become a market leader. In addition this tool has facilitated the entry of the company into new markets as the modelling processes can be adapted to a new line of products (rudders, shafts, brackets etc).

Company Partner: CJR Propulsion has combined decades of experience with modern technology and engineering prowess to evolve the finest propeller and sterngear systems available. Using innovative designs our products provide maximum power with maximum efficiency. For their size and type they give unrivalled performance in speed , fuel economy and vibration free operation. Our role at CJR is to work in harmony with motor yacht designers and builders to achieve the very best performance with efficiency and reliability.
