Dear June and all,
We have been fitting out Redshank (275/19) over the winter. We had a stainless tube attached to the rear of the rudder stock. This was free to move up and down and had the remains of a grove at the end. We say remains, because it must have been crushed by the lifted rudder and would no longer hold the rope. In fact, we almost lost a finger trying to fiddle with it and it was very difficult to reach when it dropped down.
At Brancaster, we noticed Flamingo laid up. She had a stainless rod with a ring welded on the end, through which the uphaul was led. After some fiddling, we made a prototype out of an old alloy tube and took it to our local stainless man who made a stainless replica - a solid bar with a ring on the end. He ground a slot and drilled a hole through the other end so it fitted over the D-shaped fixing on the rudder stock and added a lump below so it will only drop down to the horizontal. If it falls right down, we cannot reach it to lift it up to do its job.
We have tried it out. It was very hard whilst the boat was laid up, but easy when she is afloat.
Sorry I don't have the dimensions, but they can be found next time we visit if it will help. We can also supply the name of the stainless man, although I am sure it is easy to find a local source.
Best wishes.
