The Perfect Balance of Lightness, Strength, and Hydrodynamic Efficiency
The Dotan rudder blade is the result of advanced engineering, specifically designed for catamarans and dinghies. It combines low weight with exceptional strength thanks to an innovative production technology based on simultaneous thermal shock and high-pressure treatment. This method ensures the dense compression of reinforcing fibers aligned along the blade, significantly enhancing its strength while keeping it lightweight.

High Material Density
Dotan’s technology enables the creation of a high-density material, ensuring exceptional durability and resistance to mechanical damage.
Unique Design for Maximum Reliability
As seen in the cross-section, the integrated, powerful longeron acts as a structural backbone, providing stability to the blade even under extreme loads. This monolithic structure eliminates vibrations, ensuring stability and comfort while operating the vessel.
Hydrodynamic Profile and Durability
- NACA 0009 Profile: The rudder blade features a hydrodynamic cross-section developed by the National Advisory Committee for Aeronautics (NACA). This profile reduces wave and induced drag, improving the vessel’s performance and maneuverability.
- UV Protection: A specialized coating shields the blade material from UV radiation, extending its lifespan even during prolonged use.
Advantages for Vessel Handling
- Load Resistance: The reinforced construction withstands significant mechanical impacts while maintaining functionality in extreme conditions.
- Minimal Resistance: The blade’s hydrodynamic shape reduces water drag, ensuring smooth motion and effortless control.
