Well said, @drutter: "something dramatic, wonderful, and terrible" is going on in this poem.
It's haunting and deep, and I get mad at myself for being obtuse (as always with poetry). First stanza, I'm thinking husband in spite of the word "vessel," which might have tipped me off. Next, "abandoned craft," I'm thinking airplane. Third stanza, "water worthy," I'm thinking boat, but "well," I'm thinking of a person again. Final stanza--which is brilliant!--has me thinking of a husband or lover. Whose knife carved a place -- to put you in your place or to control? Not a boat's. I pass you daily with my dogs, master myself now, is richly provocative. She's taking control of herself, her life, her emotions. I'll have to read this many times to "get it," but even if I'm not sure what the writer is saying, the words are so memorable, I'm still rewarded for reading it. Kinda like hearing songs and never discerning the lyrics but loving the song anyway. Sorry for the ramble - this is beautiful, @owaso! 'nuff said.
