Whisper foiling catamaran adjustable rudder holder by flyinggorilla

In shallow waters one needs to keep the rudder in a middle position. This is an adjustable strap that can be quickly set and removed. When applying two of those print parts one can have two heights pre-adjusted.
The 3D printed "twister" has 3 holes to tightly fit a 3mm rope. You run the rope zig-zag through those three holes to achieve enough friction. Remember that friction is higher when there is rope tension on both sides of the twister.
At the lower end i used a 5mm bungee that is simply pulled over the T foil at the rudder. The bungee should provide enough tension so that the rope doesnt slide in the twister.
