I don't understand the Pirate (crew member) that you can throw away to avoid a punishment of an aventure. When would you pay for him? During the dice rolling turns, so in expectance of an adventure turning out bad for the players? If so, are you allowed to pay even if you don't have dice to roll? Or is it possible to pay him just before an adventure is evaluated during the aventure phase?
You need to pay him during the rolling turns, for example when you see that something won't go well. But what is important, you can pay only when you have dice to roll and it's your turn.
