Very few people who die by sudden cold water immersion actually die from drowning or hypothermia and most actually die within a few metres of safety.
Do you have a reference for this, because I've never heard it, and I'm an ER doc.
I've had a drysuit flood in 46 degree water when a neck seal went. It took 30 minutes to get back to shore. I was cold, but I wasn't hypothermic to a serious degree, and I certainly wasn't dead. Two layers of 200g quilted Thinsulate can be amazingly insulating, even in cold water.
