The Fort Lauderdale International Boat Show saw this year’s attendance jump 5 percent to more than 100,000 visitors. Exhibitors praised the palpable optimism on the docks this year, helped by the sunny weather, while yacht builders launched dozens of new models to stoke sales. The superyacht sector was well represented by boats like the 274-foot Feadship Savannah, the 200-foot Hakvoort Just J’s, and the 131-foot Sunseeker ZoZo, as well as dozens of brokerage superyachts.
