Wind vane steering for a double ender...
I am trying to figure out wind vane steering options for Nordica 30, a double ender with a keel hung rudder. The rudder is raked forward at a steep angle and the trailing edge is well rounded to make trim tab type steerer impossible to install.
So far, my options as I see them: install Monitor style windvane, with a monster outrigger and a paddle swinging way out there or figure out some kind of sheet steering arrangement.
Another idea I saw in some book was using a large counter balanced blade, that would have enough leverage to control the rudder directly. It would be useful on broad reach or a run only, since the pressure on the tiller is weakest at those points. The blade swings on a horizontal axis, with a weight to keep it somewhat level, and as the boat rounds up, it would lose it's balance and swing sideways, providing a pull on the tiller.
Has any one seen this type of arrangement. Any ideas would be appreciated
