If you only have a single row of rafts, and the walkway would be way too wide otherwise, you're short about 2000 people.
The solution I shoved gets the rafts inside the screens which protects them from the elements and it's more stealthy than your set-up.
And the biggest plus, they'll be far more accessible in an emergency since you have the entire lower flightdeck to assemble on.
Another problem with your set-up is that no less than 4000 people has to get into the rafts via ten doors and a walkway where you probably wont be able to fit more than two at a time. Not going to be easy.
