Mel, I'd be worried too. I always considered the swinger to be the transportable lake-boat version of the C-25, and felt its replacement by the wing keel in the late 80s was well-conceived.
One issue crossing The Stream is that it can create its own weather as its heat makes air rise--it's often visible from the coast. Another is when a wind with a northerly component kicks up vertical chop against the current, turning it into a washing-machine.
I probably never took my fin C-25 further than about 4-5 hours from some kind of shelter, and several times was glad for it, when the weather was not as forecast. I've punched through 5-6' white-capping chop with water flying everywhere, and felt secure--Passage was undoubtedly tougher than I was... but 50 miles out, I might not feel so secure. I'd say the practical limits have a lot to do with <i>you</i>--how do you feel about the conditions, handling, and risks. A mast can come down or a boat can sink 100 yards from the dock--that doesn't worry us much. Over the horizon, we start to feel a little differently... When running and hiding is no longer an option, I'll want to be in a Pacific Seacraft (or equivalent) where I'll be confident I can ride out just about anything.
Then again, some people like to take the risks, beat the odds, etc...
