Some racing multis, mostly French ones, cant their rig to windward but the rest of us don't bother with that as complication and cost goes through the roof.
As things (shrouds, crossbeams...) have limited stiffness our rigs lean over to leeward instead and the lee shroud goes limp. In my case it is very limp:

I have not thought much about this untill last weekend. This morning I tried to find photos I could use for measurement but only found a couple and all with me singlehandling (= low stability). The one above is the best since I am just about to fly a hull (in a guestimated 10 knots of wind).
* How much rig leaning do you see?
* Efficiency takes a hit but only a small one I guess. What about handling, like gust respons? (This comes from old Tornado hands who have told me how much easier to controll super stiff Martström Tornados were compared to the cheaper/softer boats they usually started out in.)
* A 'back-of-the-envelope' calculation I just did indicate that the 'measured' rig leaning angle above is in rough harmony with what I should get when taking wire stiffness and beam stiffness into account. Disclaimer: It is getting close to midnight here.
* The photo was shot by a friend sailing a Marström A-cat.
