Seas that could capsize a 50-foot fishing boat would make 18 hours on a life raft (in cold waters) thoroughly miserable.

It's unfortunate they didn't have a regular check-in system. Someone would have been looking for them a whole lot sooner.

These guys did quite well considering what they had to work with -- only their raft and the stuff in their pockets.

Clearly, they kept their heads and focused on the essentials, knowing they were in it for the long haul. They improvised footwear, shelter, and signalling. They found fresh water and food. And they did what they could to keep morale up, such as bathing with the soap they found.

The one big thing they weren't able to do was make fire. A Bic and a candle would have been a game-changer, precious beyond price.
