What can I do on a ferry? I'll be really bored. Ideas please?

I live on an island so I take the ferry often, and it's so boring. It's about a 1:30min ride and I never know what to do. I'm a 15 year old girl and I'm planning to take the ferry tomorrow to visit my family. I'll be riding alone so there won't be anyone to chat and hang out with.

- I don't exactly like going outside because sometimes the ferry's horn will go off unexpectantly and it's LOUD. I'm not very fond of the wind and or breathing in second hand smoke either…
- I've played the video games in the arcade so many times it's really boring by now
- The TV shows don't keep my interested for very long
- Everything in the gift shop is Way overpriced
- I can grab something to eat, but I don't take an hour and 30 minutes to eat a meal…

I will be taking the 8am and 9pm ferry and I need ideas for both trips.

During the night, I guess I could text my friends and chat but not on the morning trip. They'll all be sleeping the summer morning away haha

I suppose I could chat with a stranger but I'm a really really shy person

Yes, there's free Wi-Fi but I can't figure out anything I could possibly do. The only electronic device I plan to bring is my iPhone.

Any idea will be very much appreciated!

Listen to music, read a book, read a magazine, do some puzzles.

Play games funny movies and enjoy yourself
