Going to have to disagree with you there. Lots of modern yachts pass audits as self righting, but that does not mean they will self right in all conditions. Notebly, water ballasted sports yachts. I have seen a couple go upside down and not come back up. The beneteau however is not one of these boats.
As for multi's, at least us multi sailors are not under the false preconception that a boat will always self right
