I would have you try a short voyage before committing to crossing the ocean, else the punchline might be ‘and he spent the entire trip vomiting over the rails.’

[Hector is blessed with a strong stomach, but in those youthful travels, he’d seen the meek and the mighty alike brought low from seasickness. A miserable trip would be made absolutely hellish if Isaac be one of that number who cannot stomach the waves.]

If we were to make for the new world, we would have to book passage on a larger vessel, with a crew that knows how to navigate the open waters. You’d have to play nice.

[Or else the joke would end with them overboard or on a boat filled with corpses and no idea how to get themselves to their destination.]
