It will be years before Josh is ready to captain a boat, and a lot longer for Jake.
They may own Phil's part of the boat, they may even buy Cornelia Marie Devlin out of her half, if she wants to sell.
Jonathan, Andy, and Sig will be looking over those boys, for quite some time. And that's a good thing. I'm sure they'll be helping them find a captain to take the boat for a while.
