Survival times

[ballena]

SWMBO is getting ready for the annual pontoon sliding activity now that winter is round the corner.

She wants to know what the usual survival times in the water are, based upon today at 12C and down to 0C

Anyone know???

There was a boating accident out here 4-5 months ago. In 12C water, in exposed open sea conditions though, they started dying after an hour. At 0C, as long as you're not talking about fresh water (which gets hard to swim in then!), survival is minutes (or else immediate as has already been said).

In 12 degrees if you are of average build and no cardiac or respiratory problems, 15 to 30 minutes. If you are significantly obese, even upwards of an hour. In zero degrees, only a few minutes no matter how healthy you are.

To a large extent depends what you are wearing. If you had on a dry suit with multi layer thermals and fleeces, a heck of a lot longer than if wearing jeans and t shirt. Oilies in the water are no better than jeans and t shirt

Agree with the others, though by contrast last month my brother picked up a diver who had been in the water 13 hours. He had cocked things up and lost his mother ship (RIB) due to currents, and in 2m waves they couldn't find him. My brother heard the prob on VHF and happens to have a tall flybridge, so eventually they found him. Halfway between W Coast Scotland and Northern Ireland. He got helicoptered off my brother's boat. Sea was not quite as cold as it is right now but still pretty inhospitable. Anyway, although everthing else this diver and his party did was incompetent the one thing they got right was drysuits and fleecy stuff underneath, hence he survived as long as 13 hours.
