Therefore, the use of this comparison enhances the perception of the massive sound associated with the pack under compression.

The Ship's fury and its unpredictable behavior are made explicit through the use of a simile. In particular, the comparison of the Ship's behavior to that of a giant beast in its death agonies enhances the reader's understanding of its fury while heightening the imagery. The narrator notes: "More than any other single impression in those final hours, all the men were struck, almost to the point of horror, by the way, the ship behaved like a giant beast in its death agonies."
