Let's say there's a merchant participating in the Triangle Trade in the seventeenth or eighteenth centuries, but for some reason, his crew has managed to lose all of their provisions for the voyage from the Bahamas to the American Colonies.

What types of things would he have to buy to make sure his crew got there without mutinying for lack of food? How much of these things would he have to buy? How much would this cost him? In other words, what kind of provisions would be needed for the ship, how much of them, and how much would they cost?

I've found plenty of resources saying that sailors at the time ate mostly hardtack, salted pork, salted fish, and if they were lucky, sauerkraut to keep scurvy at bay. I've also found things like the necessity to bring both fresh water and rum to make grog in order to sanitize the water somewhat. However, I haven't found anything to tell me how much of this a ship might stock.

The reason this is important to me is because I'm running a TTRPG campaign where the players want to be pirates, and we've talked about wanting to have logistics be important, and I was wondering If I could get a baseline for which supplies they would need, how much of them they would have to buy, and how much it would cost them out of their treasure.

I understand that pirates often stole most of their supplies, but I'm still wondering how much these things would cost if they had to do it legit.

Thanks!
