The first one has a externally hung rudder and the mizzen mast appears to be set ahead of the rudder. It's hard to see how it works but I believe the mast is offset to port allowing the tiller some clearance. This picture was taken with a long lens. I didn't get very close to get a good look. It's amazing how hard it is to frame a shot with a long zoom and no tripod while the image stabalization is working hard.
