The ocean beneath them was constantly moving.
Large waves could crash against the stern of the tanker, sending spray over the men and soaking their clothing.
Strong winds made their exposed position even more dangerous.
During the day, they faced the heat and intense sunlight.
At night, temperatures could fall dramatically, leaving them cold and exhausted.
There was nowhere to hide.
There was nowhere comfortable to sit.
And there was no safe place to sleep.
