Thanks so much for your advice. I do like to keep the rudder blade up when the boat is on the dock so that there is less stress on the whole tiller-to-rudder mechanism. When you are not sailing, how do you go about de-tensioning the bungee? How tight do you keep the wing nut on the rudder pivot bolt? Does all the resistance to kick-up come from the shock cord or does friction from the wing nut still help to keep the blade down and working?
Thanks again.
