I believe the flybridge is just held down with those screws. However, if you are asking this question because you want to truck the boat, and if you will be paying boat yard rates for the work, it is cheaper to ship by sea. All the wiring needs to be disconnected and reconnected, as well as the hydraulics for the steering. These costs add up fast if you are not doing the work your self.
