In this video, we demonstrate the Rudder 25 with Blade 1, mounted on a 470-class sailing dinghy. This setup shows how the Dotan kick-up rudder works perfectly on boats from 4 to 6 meters (14–20 feet) – including dinghies, catamarans, and day sailors.
Dotan’s kick-up rudder system highlights the concept of synchronized operation of dual rudders. With a clever crossbar mechanism, both rudders can be lifted or lowered in one smooth movement. Ideal for catamarans, where dual rudders are a common feature, and also suitable for sailboats with twin rudder setups.
Discover how Dotan kick-up rudders are tested for durability and reliability. Designed for catamarans, sailboats, and Optimists, these rudders are made to handle tough conditions. Perfect for sailors who demand high performance and longevity.
See by yourself how easy you can start from any shore and how safe you can return!
In 2019, Dotan developed a new Optimist experimental rudder with a super glossy finish.
Our centreboards are made using our know-how technology. In the core of it is combination of very high pressure with thermo-shock. This technology gives our centreboards resilience qualities which are very important on a beat in choppy or rough waters.
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.
