Great comparison. More interesting - take a look at the rudder. In all cases they have the shoal draft rudder which would work with the centerboard model. This is the same thing we saw on our 51 of similar vintage. Apparently they would change the keel but not alter the rudder. Rob Ball hand some interesting thoughts on that when I spoke to him in the early 2000’s about redesigning the rudder. Curious if that is just drawings or in fact held true in production.
