I'm assuming when you say 'end scene on the boat' you're talking about the after credits scene with Kevin, Chris, and James on the yacht.
Fairly certain it's just a nod to his next big project and was a fun way to display his new logo. At least in the version I played after the scene showing the three of them on the yacht it showed the trailer for his next project. I thought he made a pretty good effort to make it clear that's what all that was about. Really just a nifty way to get that trailer out to folks who aren't following him here or elsewhere.
Hope that helps buddy.
