Re: Is external rudder a good idea?
I agree with you.
One thing about an outboard rudder is that it gets the head of the tiller out of the cockpit and this can free up cockpit space. It also moves the rudder planform aft and on a small boat this can help with directional stability.
Bob, right there are the reasons, AIUI, that Joe Adams used an outboard rudder for his highly-successful 'Adams 20' design late last century. That's 66 feet of racing yacht capable of +20 knots hour after hour in strong winds and a Tasman ocean swell.
Not sure I'd call a 66ft boat "small", but it's a relative term I suppose..
