Pop Up Rudder
I think the pop up rudder design is a good concept and we use it in shallow water, but the reality of the pop-up and the lack of rudder control when it does float are flawed. My downhaul(rudder tension line) has jammed in the rudder checks making it a pain to unjam. What seems to work for me is to feed the line thru a tiller tamer attached to the tiller and keep enough pressure on that line so the rudder won't pop up unexpectedly. a few quick loosening turns on the tiller tammer and the rudder will pop up when approaching shallow water.....on a mooring or slip in deep enough water you can use a more secure tie off for that line, as the clam cleat supplied with the boat on the tiller doesn't hold the rudder tension line securely...
