It’s kickoff season for the biggest year yet for American Cruise Lines, with more ships in more states than ever before. American Serenade, the line’s sixth riverboat, and the first two Coastal Catamarans will join the fleet. On the West Coast, American Jazz will be the first riverboat in 80 years to sail San Francisco Bay and into California Wine Country; on the East Coast, American Star will sail an eight-day Great Rivers of Florida itinerary roundtrip from Jacksonville.
