Hull scan to design bespoke flow-aligned rudders for optimum performance
Earlier this week we carried out a 3D scan of the hull of a Horizon 105 in North Carolina. Working together with our partners at Wildcat Propellers, we gathered the data in a process that takes only a few hours. Our experienced engineering team in Southampton, UK, are now running…
30,000 hours use with no cavitation issues
How do our CFD-designed, fully CNC-machined propellers save you money and reduce time out of the water? By designing them to minimise cavitation, our propellers have an extended working life (and extended replacement cycle), as testified by this recent positive feedback we received from Brian Nielsen, Technical Superintendent at DanPilot:…
