On the main deck, the Riva has one feature that truly sets her apart from the competition. Her fully carbon-fiber hardtop raises and moves forward hydraulically, to integrate seamlessly into the bow portion of the boat, which effectively means the Riva 76 Bahamas is a massive, hardtop convertible. When she debuted at Cannes, this feature, among a sea of the best the yachting world had to offer, still managed to leave many showgoers agog.
