Re: Is external rudder a good idea?
Many of Adam's designs did, especially his racers.. but the '20 was the largest of them all.
He seemed to believe that an outboard rudder was best for a racing yacht and an inboard rudder on a cruising yacht. Modern racing yacht design seems to have moved away from that now due to the 'ventilation' issues described by Rich.. but it hasn't necessarily made any difference in winning races.
