I can't find any references that jinbei actually knows Hatchan at all, aside from the fact that they were both members of the sunny pirates. But, seeing that Jinbei has returned to Fishman Island to protect it, he might have trained some strong fishmen so than can help him defend the island, we'll find out soon enough.
