Amazing that numerous folks who abandon ship (calling mayday, getting retrieved by commercial mariners or Coast Guard) do find that their abandoned sailboat makes it through incredibly large seas/winds/storm conditions after they've abandoned it. Even with knockdowns, monohulls come upright again and again, continuing to stay afloat. Inverting/Capsizing much more readily than monohulls, yes, that's the weak point of a multihull--however even when capsized, unless holed the multihull should stay afloat safely as demonstrated by the capsized multihull in the link JeanneP makes.
It is probably best to not leave the boat unless the boat is really and truly sinking.
Regarding how to get off one's boat into the life raft/ life boat? I always figured that if conditions where really that bad (AND one's boat IS already sinking), one would be able to get into the lifeboat on deck and wait for the next wave washing over the boat to take you and the life raft off the boat. However, I'd think it would be a case-by-case figure it out scenario.
