Boris,
This is almost an impossible question to answer with any certainty and the most qualified person to answer it would, of course, be the designer Dudley Dix.
For a capsize (as opposed to a knock down - mast horizontal) much will depend on the sea conditions at the time. An F6 in relatively sheltered waters will be much different to an F6 in open seas. Nearly all capsizes of displacement type yachts are caused by waves and breaking seas, not the wind strength.
From my own experiences of sailing the CC19 in races last year with F6 and F7 winds in both sheltered and exposed parts with steep seas in the Thames Estuary, was that the boat was extremely stiff and never gave any cause for concern.
I would imagine in sheltered waters it would be most unlikely that an actual capsize could occur even if sailed badly, but again this is a question best answered by the designer.
