The Dotan centerboard, made from fiberglass-reinforced composite material, combines exceptional lightness with remarkable strength. Thanks to an integrated spar inside the structure, similar to a honeycomb pattern, this centerboard provides superior mechanical properties and completely eliminates vibrations.
Dotan’s manufacturing technology is based on an innovative high-pressure thermal shock process (GRP), which far surpasses traditional vacuum-forming methods. This process ensures increased material density, guaranteeing exceptional durability and strength. The centerboard profile is based on the advanced NACA 0009 hydrodynamic design, which reduces hydrodynamic drag and induced resistance, thereby improving the boat’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.
