As a reader, this poem carries a lot of emotional weight which trails behind the person. The writer wants to make it right wants to heal but how when the writer itself feels wrecked. Maybe I'm wrong about the impression of this poem but it's what I feel...take care

"Full it was,
Of things I didn't need.
Grief, sorrow and things I will borrow"
- these are my favourite lines. For me, it shows how the person possessed many things but was not satisfied, and kept looking for that one thing he wanted. But when the person finally finds it, it is too late; he realizes the value of everything but the damage has already happened.
And I love the ship metaphor!
