This is an overly broad and badly made generalization. There are many swing keel or centerboard boats that are quite seaworthy. In a recent thread, the subject of centerboard/swing keel bluewater boats came up, and the Ovnis were mentioned. These are very well regarded centerboard boats.
Of course it was... But when you say "swing keel" what is the first thing that comes to mind? This is not the same as "Keel/CB" of which many capable blue water boats were built as. There are comparatively very few SWING KEEL boats that were built for anything other than lakes.
So here is what Lostmt's boat has "...keel down draws 6'/775 lbs and 1'11" up. "
The original question was what do you do if you are TOO FAR TO GET TO SAFETY and you are in heavy weather, which I assume means stuck in the middle of a large open body of water somewhere and the stink blows in. Would you ride out storm force winds in the ocean in a Catalina 22, a Venture, or even a WW Potter? Sure a WW Potter can sail to Hawaii, but could it survive the stink. How did the guy sailing the Aquarius 21 (715lb swing keel) from Hawaii to Alaska fair? Thats right.. he is dead. Seriously...

Edit: Skip Allen scuttled based on an opportunity to do so presenting itself. Almost everyone regards his decision to leave a perfectly good boat, equipped to handle offshore conditions, as a good one. Wonder how things would have been different if he were in a SWING KEEL boat with a 775lb keel... hmmm...
