1. Put the boat on stretchers

2. Loosen the screw circled by red

3. Make the rudder straight by hand, by lining it up with the fin. Eyeball it the best you can and have somebody keep it straight

4. Set the shoe straight - how you want it to be when the boat is going straight.

5. Take the two cables, circled by yellow and pull them as tight as possible.

6. During step 6, make sure neither the rudder nor the shoe moved. If they did, set them straight again while holding the cables tight.

7. Tighten the screw circled by red.

A single experienced person can eventually do this, sometimes on the water, but to start, having three people involved helps.
