I want to create a boat that floats across an ocean for an animation something like this in Moana: https://gyazo.com/b6bae882baad57b4da22549bb50ade43 but I just can't figure out how to combine the ocean layer with the fluid domain. I have been searching for days I found a description of what I'm looking for but he didn't explain how one might do it here's the link to the thread that describes it better than I can: Is the ocean modifier better than the fluid simulation for making an ocean? I would love to hear from someone who knows how the big studios do it.

Here is a complete tutorial on how to combine ocean modifier and fluid sim to generate exactly what you are looking for: https://www.youtube.com/watch?v=qVwfEHtLiyI
And here is a simpler version just with the Ocean Modifier (for zoomed out shots for example): https://www.youtube.com/watch?v=smArCTzxGpE
Both techniques can be combined but tend to be resource-intensive when rendering. I would move between two scenes (close and wide) to optimize.
