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

It really depends a lot on the loads the tiller will experience... a pure windvane doesn't generate much force to steer the boat, so you the servo-pendulum or trim-tab models are designed to generate greater steering forces. Might well be worth reading Lechter's book on self-steering.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Hi, Im looking at a Cape Horn model for my Union 36 canoe stern, so far it looks the best and has a 5 yr (or one circumnavigation) guarantee!

Cape Horn

I have a Cape Horn on my pearson 33. I love it. I've sailed just over 3,000 miles with it in the last 5 years and it is really tough. By far the simplest and most robust design. I carefully looked at the others and felt they had flaws I could not live with. (too many moving parts, not sensitive enough, mixed metals, poor service, looking like oil derricks on my stern, too fragile, etc.) I also went to Montreal to visit his factory. Yves is a genius, and does very tough, quality work. All stainless and simpler to mount. I really like steering the boat from inside the cabin with it. Plus it was a good buy.

FWIW I recommend it.
