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
