We took a little cruise last year, Inland Passage, and in Ketchekan we had to anchor out and use the lifeboats to be ferried to shore. I was pleasantly surprised to see that the hard hulled, motorized, boats were fully enclosed, had lots of floatation (even tho in a real emergency we would all be wearing those really neato PFD's that they have in all the rooms). I also spotted lots of boxes labeled "Food," "Water," etc, and there was a two way radio built in. So I think that my main priority would be nice warm clothing...
