The Dotan centerboard, made of fiberglass-reinforced composite material, offers a unique combination of lightweight design and exceptional strength. Thanks to the integrated spar inside the structure, similar to a honeycomb framework, the centerboard provides outstanding mechanical properties and eliminates vibrations completely.
Dotan’s production technology, based on high-pressure thermal shock (GRP), is significantly more effective than traditional vacuum-forming methods, as it results in a much denser material, ensuring superior resistance and durability. The centerboard profile is based on the advanced NACA 0009 hydrodynamic shape, which minimizes wave drag and inductive resistance, enhancing the vessel’s maneuverability and performance.€ 380

Optimized Rudder for the Optimist Class Our engineers have designed a rudder specifically for promising racers in the Optimist class. The unique construction of this rudder will help future champions achieve outstanding results faster. Advanced Manufacturing Technology The rudder is produced using advanced technology that combines high pressure with thermal shock. This method significantly increases the compression of the fiberglass laminate compared to traditional vacuum molding techniques. Key Benefits of High Compression: Layers Form a Monolithic Structure: The fibers of each layer bond seamlessly with the adjacent layer, creating a uniform material without weak points. Improved Strength, Rigidity, and Durability: The rudder demonstrates exceptional resistance to loads and wear. Enhanced Resilience: Its ability to quickly return to its original shape after stress ensures superior flexibility, especially critical when tacking in waves. Included Components The set includes a rudder and rudder fittings, ensuring full readiness for installation and use. Ideal Profile and Hydrodynamics A smooth, high-quality surface finish on the rudder reduces water resistance, increasing speed. The cross-section of the rudder is based on the NACA 0009 hydrodynamic profile, ensuring superior stability and maneuverability. Compliance with International Standards The rudder is fully compliant with the latest IODA rules, ensuring its suitability for international regattas.
