Very interesting discussion here...have been listening to Nina Simone's "See Line Woman" for the past few days and trying to figure out the reference. Upon beginning my search on line for the lyrics I ended up here and glad to know others share the same interest in the song. Don't know the Ship sisters but will certainly research. My initial take {aside from the fact that I found myself dancing to the tune in my studio with wild abandon} is that it's merely about a "siren"...often associated with the sea and their ability to lure men towards them resulting in the wrecking of ships against the rocky shores.
