1) We've been doing this for years, just using a water "still", not the raft itself.  But neither a still nor this raft are or will become mandatory on ocean-going vessels.  As long as it floats, it fulfills the requirements.

2) A length of line and a fishing lure and some hooks (use the lure to catch the first fish, then use the inedible parts of the fish as bait) will serve the same purpose.  Ocean fish are full of fresh water and most are safe (and pretty palatable) to eat raw.  The problem is that most people don't know that they can stay alive at sea for a very long time just eating a few fish (and some supplement pills for missing nutrients) a day.  "Bathroom" facilities would pose a larger problem for most mixed-gender groups (at first).

I don't know if you've ever read it, but this book about sea survival is incredible...

Steven Callahan survived 76 days at sea in an inflatable raft. Incredible story... lots of discussion about how to make fresh water, catch fish, and in general, not go bonkers.

Thanks for the recommendation, I've been looking for something like that to read in the pool.  :)
A cynical habit of thought and speech, a readiness to criticise work which the critic himself never tries to perform, an intellectual aloofness which will not accept contact with life’s realities â€" all these are marks, not as the possessor would fain to think, of superiority but of weakness. -TR
