keeping in mind that I don't have kids, I do like version #1 if handling isn't compromised with the stubby rudders. Can you imagine it on the trailer? You can completely leave the rudders in place AND you lose all the complication with a rudder up and down system.
Jake:
Spade rudders will be to short. THINK about what happens when of your rudders kicks up while sailing now? EVEN on my little 4.3, which at 240 lbs is 160 lbs or so lighter than your I-20, I get weather helm like hell with it up, even though some is still in the water. PLUS vibration and wind flapping from trailer speed would beat them to death. I am constantly advising newbie to take there damm rudders off and put them in box or car. Friend has his run into with rudders on and wiped them out.
Just my 2 cents,
Doug
