The Dotan® Kick-Up rudder has been designed to use with sailboats and catamarans (length between 5 to 12 ft.)
The Dotan® Kick-Up rudder box manufactured from Glass Reinforced Polyamide and it has Ultraviolet (UV) protection.
The Dotan® Kick-Up rudder blade is manufactured with unique technology (know-how) of high pressure and simultaneous thermal shock. The rudder blade has special hydrodynamic design and smooth surface finish to minimize resistance forces of water flow, and this feature increases Optimist high-speed sailing capability. Dotan® Kick-Up uses the NACA 0009 hydrodynamic profile design basis for the rudder blade cross section design and it has 14mm thickness.
The rudder blade has a coating for UV protection.
The kit is supplied with a tiller. Tiller has been fabricated from 28 mm diameter and 1.5mm thick aluminum pipe and it has been deep anodized to protect it from marine environment. An end cap is placed at end of the tiller to stop water ingress in the tiller.
The gudgeons have holes of ø8 mm.
Sailors can adjust the distance between the upper and lower gudgeon, thereby enabling compatibility with diverse boat transoms/sterns. The upper gudgeon can be moved along the rudder box track. Position it according to your boat's specific transom/stern dimensions and fix it in the track by screwing in the four screws supplied.
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.
