Sounds like GURPS Boat of a Million Years!

Ok so we have:
2 guys with HT 14, Very Fit, Regular Regeneration, and a comfort zone of 7F to 104F.
For simplicities sake I will assume 12 hours of day within their comfort zone and 12 hours of night below their comfort zone.

Assuming we have 30+ mile an hour winds they roll every 20 minutes (10 minutes X 2 for Very Fit), that's 36 rolls over 12 hours. Having HT 14 +2 for very fit and being naked means their based roll is 11. Temperature Tolerance means they roll at a -1 penalty for every 10F below -28F:
-28 = -0
-38 = -1
-48 = -2
-58 = -3
-68 = -4
etc...

Assuming the temperature is -67F they will be rolling at -3, giving 8. meaning they will fail 74.1% of the time. After about 20 rolls they should be roughly at 0FP, meaning any more FP lost will cost HP as well. The remaining 16 rolls should cost them roughly another 12 FP and 12 HP. those 16 rolls take place over 5.333 hours. After the first hour they regain 1 HP, meaning they regain 4hp in total by the time day comes, at which point they regain the fatigue in just over 2 hours and the HP in just over 8 hours, allowing them to repeat the cycle again the next night!


If you use the Frostbite rules from High-Tech then things get nasty!

Frostbite is acute somatic damage to exposed flesh caused by freezing. It’s distinct from FP and HP losses to hypothermia (see Cold, p. B430), which represent metabolic damage. The two effects can and often do occur simultaneously! At the GM’s option, those exposed to freezing conditions lose 1 HP on any exposed hit location per FP lost to cold. This can cripple extremities or even limbs, and is cumulative with injury due to hypothermia.

Since they're naked that means losing 12+ HP for every FP lost! They need shelter or they will die for 1 night!
