The secret voyage is naturally quite dull, even for well-trained crew members, such a monotonous journey can be quite hard to endure.
Typically, the captain would allow the crew to relieve stress through the consumption of indulgent goods.
This is also one of the reasons why sailors were mostly drunkards during the age of sails, because at sea the only things they could use to relieve stress were alcohol, goats, and good-looking crew members.
In the original world's Cape Town in Africa, a good goat could fetch an exorbitant price.
For the captains of that era, missing a couple of barrels of fresh water wouldn't kill anyone, but missing a goat would be a serious problem.
Thus, in Europe's religious myths at the time, the devil grew horns and hoofs like a goat.
