Motor boat rudder blade

Rudder profile and sections are carefully selected to the specific regime of the flow around sterngear. Streamline low drag sections are used for low and medium speed vessels and wedge sections for high-speed boats to prevent early stalling. Rudders can be tailored to the hull using the latest design techniques including CFD to determine the accurate flow into the rudder from working propeller. Detailed hydrodynamic loading is calculated to assess rudder stock and blade strength by FEA as well as supporting bearings reactions. Design and manufacture can be done to any classification society rules including all IACS societies. MANUFACTURING Cast rudders are made using our precision tooling and cast in either aluminium bronze or high tensile bronze. Rudder cell Balancing 350 kgs of a spinning Aluminium Bronze rudder takes years of development and experience combined with the latest technology. We deploy a cell of 3 axis CNC lathes that are dedicated to machining our range of cast rudders in a single set-up. They are capable of machining rudders weighing from 20kg to 350kg. Fabricated single plate or streamlined shape rudders are manufactured and welded in stainless steel, mild steel or aluminium.
