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.

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.
