And which boat will be better for strong winds and severe 
offshore conditions?

No open keelboat will survive "severe offshore conditions". Big breaking wave, swamp, sink. 

I can easily imagine dragons sinking in severe conditions...
Would open keelboats with double floor, e.g. Dyas have a chance?

Lovely boats, Dragons, but plenty have sunk in a good deal less than severe conditions.
I once sailed a Daring that had spent several weeks at the bottom of the Solent before being lifted. A rather spooky feeling.
Any open keelboat is going to sink if it takes a large breaking wave. That's why boats designed to sail offshore have to have the ability to seal the companionway.
