of course, boat design evolves.. nothing new or special about that.None of the boats that were actually built were ever optimized for lifting rudders. That would be a pretty dumb move to build a boat around a feature you know you can't have.
What we meant is they did the study and used it as a starting point before adapting it to a configuration without lifting rudders. The results of that study undeniably influenced the designs and they took it as a starting point for some of the boats but of course they totally reworked it, in part to account for non-lifting rudders.
For instance, I'm quite sure today's boats have a lot more rocker and the bows are wider/flatter than what was studied for the "Super 60".
we are effectively on to 3rd/4th generation imoca foilers now.. so of course they are different.
