Awww. Fun.subject -too bad it's so old!
One thing I didn't see anyone pointing out and that no advertisers ever.bring up is...
If you are in weather big and bad enough to turtle you, it's not gonna be calm.
I know that sounds self evident but soooo many arm chair sailors seem to forget that a sea with a wave big enough to flip you will keep moving the boat around in extreme ways.
Which means it doesn't need to "right " itself from.some specific angle. Rather it only needs positive buoyancy and a heavy.keel.
Releasing all sheets certainly helps a good righting boat.to pop back up too!
ps.
The ideas behind multhulls was that you'd passagemake faster and be less exposed to adverse risk of this to begin with.
