There'd be a pool of dead air captured for the air to skip over.You can see this in the original video of Spirit at DARKO.
We can't really reduce the wetted area,since we're in a single fluid environment,unlike the boat hull's natural dual-fluid environment.
And Reynolds number is the same,as it's simply a function of vehicle length and velocity,which isn't altered.
I think there is a window under the louvers, so it is essentially sealed.
