I must be making progress because I did about 45 minutes of sanding and then flipped the rudder over, today. The second side got it's first layer of fairing spooge... router shavings in epoxy for the areas where I need to build some volume quickly, and wood dough in epoxy for the little stuff. I expect there will be two more iterations of this.
Also, the foil template for the emergency rudder is done.
