And what temperature was the
water?

I said above, 0C. There was ice floating on the surface. Last time I looked at my thermometer watch in those conditions, it read about 0.3.

Water temp 0.3 C Exhaustion/unconsious 15 mins, survival 45 mins.

TBH rather too consistent numbers for my liking of web sources but
fit with memory from other sources.

I've seen times quoted from 4 minutes to 15 minutes for death, and this site says 2 hours: http://wildernessmedicinenewsletter....n-mythbusters/

I've swum in 0C for 2 hours as I said, and I was neither unconscious or dead. In fact afterwards I ate a sandwich then jogged home across the hills.
