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.
