Bonaire’s underwater world gets a sense of wonder aboard this historic vessel with an explorer’s past. Once connected to the spirit of ocean discovery, the trimaran now offers a relaxed way to experience the Bonaire National Marine Park from above and below. Settle in as the vessel sails along the coast, then head to the air-conditioned underwater observation deck for floor-to-ceiling views of coral gardens, tropical fish, and maybe sea turtles gliding by. Guests who want a closer look can snorkel at a protected reef stop, while others can unwind on deck with a drink. It is part marine adventure, part floating history lesson, and all Bonaire, wrapped in a rare kind of island perspective.
