Yeah. I think that Captain, while being brave enough to “go down with the ship” as it were, is also smart enough to outwit these pirates.
He is the one that knows all about the boat, is probably in better physical condition than the pirates, is used to hard work and little sleep. I think in another day or so he’ll have the upper hand.
I’d be telling them that the rations were made of pork products. If starving they would eat it but I suspect they would hold off long enough to weaken some.
