is there an example of a metaphor or similar in this poem?

Question

Nobody heard him, the dead man,
But still he lay moaning:
I was much further out than you thought
And not waving but drowning.

Poor chap, he always loved larking
And now he's dead
It must have been too cold for him his heart gave way,
They said.

Oh, no no no, it was too cold always
(Still the dead one lay moaning)
I was much too far out all my life
And not waving but drowning.

or is there an example of persuasive language enjarment or hypothesis.

Answer 1

Maybe the whole poem is a metaphor, or a conceit as they used to call these kinds of extended metaphors.
Its about a man who like to challenge things and now he went out too far. Enjambment just means one line runs into another without a comma or any other punctuation mark to "stop" the line. The poem has quite a few of those.
I don't see any persuasive language or hypothesis.

Answer 2

I assume you mean "simile" and "enjambment." No, I don't see any examples of any of the devices you needed to include.
