When Zeref used the spell, it blew a hole through the ship and Hades fell through it, into the ocean. Also if it was still on the ship and Fran found it there, then I'm surprised that he didn't find Zeref on the ship as well. Either Zeref is a Master Ninja, Fran found the ship abandoned in a random place, or Hades was sent into the ocean.
