I've confirmed the answers, and if no one else gets them in say, 24 hours from this post, I'll post what they are, and I'll start digging for another ship to post.
Left to Right:
Yūshin Maru No. 3
Nisshin Maru
Hiyo Maru
This is really close because you're almost right. It's a bit of a nitpick, but one of those names is not correct for the date of the image. At the time that image was taken, Hiyo Maru wasn't yet Hiyo Maru, she was still Oriental Bluebird.
I'll let you have this one because my image is going to be easy to guess.
