174. You are at sea in an inflatable liferaft. In high latitudes, which presents the greatest danger?

Hypothermia poses the greatest immediate danger in high-latitude survival situations due to rapid heat loss from exposure to cold air and water, which can be fatal long before starvation becomes critical. Liferafts provide protection from the elements, and collapse is typically caused by damage or malfunction, not solely low temperatures. Asphyxiation from a closed canopy is unlikely in modern, ventilated liferafts.
