Dotan`s rudder benefits

  • Flick-of-the-Wrist Magic

    Dotan's conceptually brilliant rudder mechanism enables you to set the blade with a simple flick of the wrist.
  • Rudder Box: Constructed of Non-Corrosive

    Incomparably strong and matchlessly durable, using non-corrosive, composite materials which make the Dotan rudder box more steadier against dynamic loadings than aluminum boxes.
  • Blade Shape: NACA Hydrodynamic Profile 

    The Dotan rudder blade's profile is designed on the basis of the NACA 0009 hydrodynamic profile (National Advisory Committee for Aeronautics). The Dotan rudder blade's shape minimizes wave and inductive resistance.
  • Encountering obstacles

    When hitting underwater obstacles such as rocks, sandbanks, jellyfish, etc., the blade automatically kicks up.
  • Warranty

    Your Dotan rudder system comes with a 3-year limited warranty for the rudder box and with a 2-year limited warranty for the blade. The rudder box for Optimists has a 10-year limited warranty.
