Rudder fix
I have a C22 with a kick up rudder that would work itself up while sailing. That would cause a big problem, lack of steerage. i would not be able to just push it back down, because of the bouyancy. I had to step over the stern rail and stand on it to return it to the proper position. I had two options. First, I could have drilled a hole and thru bolted the rudder to make it a fixed one. Not ideal. I bought a piece of the heavyist bungee cord I could find. I drilled a hole on the forward edge of the rudder just below the aluminum assembly, but above the water line. I finished it with fiberglas resin to keep the rudder watertight. I fabricated two clamps out of alunimum metal to attach to the sides of the alunimum rudder assembly, just below the tiller pivot point. I put the bungee thru the hole in the rudder and clamped it at both ends with machine screws that were already there, tightening the bungee before final clamp down. I have never experienced a single episode of rudder creep since then. I still have a rudder which will kick up in the event of a grounding.
