Hypothermia question

[garrypallister99]

Hi, just two quick questions.

1. If I weigh 90kg, how much weight will I need in a backpack so that I sink in water?
2. If I do not sink for some reason but am in the seawater for 7-8 hours will I die of hypothermia anyway?

Thanks to whoever reads this

Ten percent of body weight upwards. You will of course float up later on.

The hyperthermia must depend on the water temperature. You'd more likely drown in any case. In freezing water, you can die in tens of seconds.

Thanks very much for the reply. Fear of failure has me asking every possible question

tens of seconds is unlikely. I watched an "I survived" documentary show where someone falling off a sled into ice water took 10 mins to almost lose consciousness.

Less than a minute might be the case for hot springs, assuming the water is actually boiling, but that is very painful.

It depends on the water temperature, but if you're in the seawater for that long you'll probably drown anyway.
Just a heads-up: dying of hypothermia is a lot harder than it sounds on paper. I tried this weekend but it was too dang cold.
