Why do you say that? I'd say the foretriangle matches the mizzen quite
well.

Lots of forces in play here, Navvie©. The horizontal distance (in two axis
as the boat heels) between the sails CE and the boat's CLR, the torque
developed by the hull & foils, etc etc.

If you're talking about Mari-Cha 4, it looks to me that the mizzen is far
bigger than the foretriangle.

If the C of E of the main matches the CLR (as it should for a
balanced ketch) then she will balance under miz and foresail.

Sure.

"In theory there's no difference between practice & theory. But in
practice, there is."

Not all ketches balance the way they should. Possibly due to different
priorities on the part of the designer, possibly by error, whatever.

Yes, the miz is bigger but the moments look similar -right?

Doesn't look anywhere close to my eye, but they could be anyway.

Obviously a lot of very careful engineering went into this boat. The question
is, is balance under jib & mizzen on the list of design priorities, and how well
did they achieve it?

Well I see it like this: Why not go for balance. If the main blew you
would not want a horribly unbalanced racing boat!
