Hard to imagine that they couldn't stay alive for a single night.

The winter I spent in Minnesota was one of the coldest on record. A
resident hopped out to get his morning paper, got locked out and froze
to death. His tracks showed how he'd walked around his house trying
windows then started for his neighbors house. After some 20 yards he
circled away, apparently loosing it, and fell ... all in minutes. I know
it's never that cold on the water but ...?
