Personification Definition: 
Pretty much give or compare an inanimate thing with human qualities.
 Examples that come out in the poem:
"Puts an arm of sand in the span of salt" It compares the sand with an arm.

Hyperbole: An exaggeration.
Examples that come out in the poem:
"The lucid and endless wrinkles" The waves won't be endless, so it's somewhat of an exaggeration.

Metaphor: Similar to a simile, but without like or comparison words. A figure of speech.
Examples from the poem:
The answer to the first one (personification). Compares sand with an arm, without like or similar.

Alliteration: A series of words with the same first letter
Examples from the poem: 
"Shadows of Ships" both start with SH. "Low blue Lustre" Both start with L.

Repetition: Reoccuring things. 
Ex: In the beginning of the poem, it says Shadows of Ships. Says the same thing in the end. The sense of beginning and finality?

I don't know if this helped. Hope it did :)
