The yacht has dramatically raked windows forward and the flybridge follows suit, giving her aggressive lines. Her flybridge is positioned amidships, allowing for an electric sunroof just forward of it over the salon and main-deck helm. This setup, says Prestige, makes the 680 S part flybridge and part coupe, offering the benefits of both design styles. She has a U-shaped salon aft up top and dual helm seats are on centerline forward. Another companion seat is to the right of the helm.
