Final answer:
The question seems to involve a confusion with the character Beowulf from the Old English epic, whereas the references provided are about different characters' experiences at sea. None of the passages specify how long characters sink before seeing the bottom, focusing instead on their intense struggles with the sea.
Step-by-step explanation:
The question relating to how long Beowulf sinks through the water before he sees the bottom appears to be a misunderstanding since it is not Beowulf but characters from tales of sea adventure who have experiences with deep water and dire situations. Your references are from different sea narratives, involving moments where characters are in deep water or in peril at sea.
Within these passages, there is no specific mention of Beowulf, a character from an Old English epic poem, sinking through the water. Instead, these passages describe scenes of characters struggling at sea, dealing with the overwhelming power of the ocean, and the prospects of survival in dire circumstances. The extracts mention the cold, deep waters, long periods under water, and the challenge of emerging from the depths to reach the safety of the shore.
It is not clear how long any character sinks before seeing the bottom or the potential rescue as the passages do not state specific durations. Instead, they focus on the intensity and struggle of the characters' experiences with the vast and powerful sea.
