Hi, Mike -
Given the tentative nature of the ID so far, I would also be thinking about House Crow, which also has black head and gray underpars, etc., although not quite so contrasting. I think House Crows ride ships more often, and they occur in places that might be a direct shot across the Pacific without encountering land (where a Hooded Crow or other European bird might be expected to disembark).
Steve Howell et al. discussed both Hooded Crows and House Crows in Appendix B of "Rare Birds of North America." They seem to draw a different line than the ABA rule: they tend to discount species likely to be provided food on the ship.
in any case their discussion is worth reading.
