You know, it's a pain to translate from my phone xD
I'm not going to translate the full chapter but at least this:
Yamato: For me, that I'm Kouzuki Oden, I kept up with the news thinking that you, who are Ace's young brother might take me on board.
Luffy: You again! Kouzuki Oden was loved by everyone! There is no way it's okay for you to become Oden!!
Yamato: Well maybe you are more Oden than I am!!
Luffy: What does it means that I'm more Oden than you?
Yamato: Even if I'm Oden, I'm not 'free' due to these handcuffs! I wanted to go out to sea with Ace and the others... But I've been confined in this island since I was 8 years old!!
Luffy: Is that what they put on the prisoners?
Yamato: Exactly! It will explode if I leave this island! To be honest, I think that it may be a lie... I mean would a biological father blow up his own child!? But, thinking in the worst case... Makes me freeze... That guy is my father after all!
Luffy: Should I take them off?
Luffy: Do you really want to fight with us? I'll beat your father even if it's in front of your eyes you know?
Yamato: Even I would like to do that! How many times have I been beat up by him since my childhood? Every time I challenged him I've got beaten.
Luffy: Okay, I'll take them off
Yamato: Wait, take them off? These things have been stealing my freedom for 20 years...
