This is very difficult to read after the lines:

"Lullaby curse", I don't get the connections between
A fisherman's nightmare
his wife's worst fear.

Is my interpretation of this piece correct?

I think that a person made the purchase of
a boat, and his wife fearing that
the lure of riches and gold would take him from her, either
through some misadventure or his thirst for adventure taking him,
and he just would not come back.
Now, not knowing his fate, she sits and drinks
and keeps the light on for him in case he ever comes home.
Sorry that this poem is not that intelligible.

I like the story, but you have to make the lines connect better.

it starts out okay, but does not follow through.

There seems to be multiple stories going on. I get a sense of fisherman going out to make his living and perhaps for one reason or another he doesn't return. Or it seems said fisherman is lured by a lover, an affair in which he chooses to abandon his family. I don't understand the lines she is not at home. Who isn't at home because at the end it says she waited, drinking to cope with the abandonment? It sounds like she left a light on hoping he would return. It was hard to read and follow as I wasn't sure what was happening.

and wondering, LULLABY CURSE!!! but couldn't catch up the whole scenario in the poem. The ambiguity of the poem allows several interpretations. I agree with the three above comments.

I'm sorry, what ultimately makes a poem bad is the failure of a writer is to convey that deep and moving experience to his reader that led him to write the poem.

A lot. The towards the end of it lines rang true to me the mosr:

“ Eighty years was how long she was able to wait
Held up by hope
Drinking to cope with being alone.”

My only suggestion to do would be to put a pause in places with a stanza break along the way, to allow the reader.

Nice piece.
