Dotan's Kick-Up Rudder Wooden blade racing version
The Rudder is designed for use on dinghy and catamarans 5 ft to 12 ft The set includes a UV protected rudder box made of polyamide with fiberglass reinforcement. The blade is made of high-quality Okoumé plywood and is covered three times with varnish of high strength and wear resistance. The Dotan rudder blade's profile is designed on the basis of the NACA 0009 hydrodynamic profile and has a thickness of 14 mm. The kit also includes an aluminum tiller with deep anodizing, durable and lightweight, made of pipe ø28 * 1,5mm. At the end of the tiller, there is a cover that protects against water ingress. The Dotan rudder has equipped with upper and lower gudgeons with pintles ø6mm. On the rudder box, there has a retaining clip that holds the rudder at the stern of the Optimist (boats).
The rudder parameters (dimensions and weight) meet the basic requirements of the new Optimist class rules. However, this rudder will not be authorized in certain competitions, in particular those in which the IODA rules dominate, only because of the presence of the blade lifting function, even when it is deactivated by a locking pin!
Sale! When ordering the rudder, the tiller extension is available with discount up to 55%.
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.
