The Grande Mariner of the American Canadian Caribbean Line was docked at the Landing Thursday. The “Small Ship Cruise Line” was on its way to Charleston, S.C. to pick up about 80 passengers — it has the capacity for 100 guests — for its Southern Antebellum cruise. Jacksonville is the final stop on the cruise, which includes stops in Savannah, Jekyll Island and Fernandina. The cruise company has been in business for 43 years and is headed by President Nancy Blount.
