Ackster was fortunate. No one had been able to buy the outrageously expensive boat he sold for a fraction of what the wharf was selling it for. So, he took it back by force. No one could stop him, and by the time they had gathered forces to try and regain the treasure they lost, Ackster was already far out at sea, fishing.
Since nolding what remained of his skeleton would take time, most likely more than fighting creatures of the ocean until he reached enlightenment, that's where Ackster started.
Without his skills, the process wouldn't be as rushed and straightforward. Ackster would heal slower, and since he didn't have Strong Body, Monster Muncher, and Iron Stomach to boost his metabolism and recovery in conjunction with Stubborn Well-Being, he wouldn't need to eat quite as much. But he would still need to eat.
