Re: Is external rudder a good idea?
I think you will have many happy years using that rudder as long as you keep an eye on it.. like anything else on a boat. Do the Maintance and repairs and she will keep you happily afloat for years.
I am a big fan of Cat boats. Those veseels have -huge- "barndoors" for rudders usually. With them you cannot just hard over the rudder to tack, but should do a more calm arch through the wind. With a rudder that size, it does not just stall, but turns into a brake
