In response to JokerJay779, It's not directly stated. If you think about this way, DIO's Coffin was on the sea, and would have been discovered right before part 3. It was opened with a blowtorch. If the coffin was originally in the water, then that means the coffin was ditched after being opened. Right after the fishermen found it, Pucci would be fifteen, following how the timeline went. Dio probably didn't want anyone to know about him except the original people who opened the coffin. Then this slowly leads over to Pucci becoming a priest following DIO's heaven, then into Stone Ocean. If the original ship was the one that picked up the coffin, that means that either it took place on a ship, hence the name Stone Ocean which could have been referencing Pucci's original life.
