Summary

Sometimes you are missing a hand on an Archambault Surprise 25!

This thing allows you to fix the tiller extension and the rudder in case you quickly have to do something else. It is screwed on top of the hinge of the hatch.

The noses cramping the tiller extension tend to break away in case you lean the hatch against them - so careful. Printing with TX-CF20 or something similar helps.
