Treading water for 20 hours is impressive.

But life jackets would have been easier.




Makes me glad I bought a Boston Whaler. It may turtle, or burn to the waterline, but it won't sink.
Here is a cool story about a whaler that was blown off its yacht (it was one of the tenders) and was adrift for over two years!
