I have never, on any tour boat, pleasure boat or ferry, ever seen any passenger ask for and wear a life jacket. The only exception is charter boats crossing the bar and then once clear of the bar they often remove them. Other than that, never. Why are you implying something that never happens is common?
"Why are you implying something that never happens is common?"
I didn't say that at all.
What I said was
"Luck favors the prepared."
