She is the vessel at anchor on the top left
This vessel had painted with very big letters Vicente Suarez on the forward quarter, so she seems clearly related with this owner Vicente Suárez. As I don't find any data about her, and having in mind the letter size not usual for a ship, maybe she was a kind of pontoon, could be for coal bunkering. All the fishing vessels were steamers, what indicates the photo time.
