What things would you have taken on your trunk across the Atlantic, Why?

I would bring a small knife, ( for protection of course), a sweater because it can get a bit chilly out at sea. Maybe a little gift for my family. I would bring a telescope to look out at sea, a book so I could identify the animals I see, and if was now in the modern 'ages' I would definitely bring entertainment, a book, iPad, and other objects.
