My dad was in the merchant navy 60 years ago and I think boredom was an issue then. I know they had some movies to watch, but they would get through those on a long voyage. I think there was a fair bit of drinking going on. The olden pirates might have had some guys who could play music for a song and a dance, but who can stand weeks of sea shanties? I expect few of them could read and voyages could last years. Again, drinking was probably popular.
